Abstract
Nano-metal-phosphonates are used as an inhibitor to prevent scale formation in water processes such as water desalination and in porous media inhibition processes using sea water. The use of such inhibitors in all mineral scale inhibition applications is proposed because of their better inhibitory effects. The nano-Ca-DTPMP (nano-calcium-diethylenetriamine penta(methylenephosphonate)) particles are synthesized and utilized in CaCO3 scaling inhibition experiments. The precipitation/inhibition curves were obtained through the online electrochemical measurement of Ca2 + concentration and pH against time. Moreover, the Field Emission Electron Microscopy (FESEM) analysis of the CaCO3 formation precipitates is carried out to study the crystal shape and morphology changes. The results show that nano-Ca-DTPMP inhibitors delay the precipitation of CaCO3, decelerate the Ca2 + and pH reduction and increase the final Ca2 + concentration in the bulk solution. This occurred because of inhibitor particles interfering into the calcite crystals and significantly changing the shape and morphology that is confirmed by the FESEM images of the precipitate formation. The inhibition effect enhances by increasing inhibitor concentration from 5.6 to 11.2 ppm. It is found that at the same concentrations, the inhibition influence of the nano-Ca-DTPMP on the calcite precipitation is effectively more than that of both micro-Ca-DTPMP and the commercial DTPMP.
For example, diethylenetriamine pentakis (methylenephosphonic) sodium salt (DTPMP-Na), an organic phosphonate salt with five phosphonate groups, is widely used as a good peroxide stabilizer, oxidizing bactericide stabilizer and superior corrosion inhibitor for antiscaling of boiler water. 30 With aforementioned advantages, organic phosphonate salts are expected to be good candidates as draw solutes for FO applications. To the best of our knowledge, however, no study has been reported on OPS as draw solutes in FO process yet.Diethylenetriamine penta-(methylenephosphonic) acid (DTPMPA) is a typical scale inhibitor used in the water treatment process [17]. The high phosphorus content of DTPMPA (22%) can offer a good fire resistance to polymers. ...The material commonly used for scale inhibition is diethylenetriaminepentatakis (methylene phosphonic acid) (DTPMP). Recently, Ca-DTPMP nanoparticles have been used for scale formation inhibition, and it has been shown that the effectiveness of these nanoparticles at equal concentrations is considerably higher than their commercial counterparts [52]. . In cooling water systems and desalination processes, where CaCO 3 scaling is a serious problem, DTPMP is predominantly utilized as scale inhibitor. Current scientific developments highlight the utilization of nano-Ca-DTPMP with enhanced inhibition of calcite precipitation, which can serve as new low dose mineral inhibitor
The strong adsorption of CNTs caused the scale inhibitor to have longer retention and a higher adsorption concentration. A nanostructured scale inhibitor, Ca-DTPMP, based on diethylenetriamine penta(methylenephosphonate) (DTPMP), was prepared by Kiaei et al. [30] and its effect on the growth of calcium carbonate in bulk solution was studied. It was found that Ca-DTPMP nano-inhibitors can increase the concentration of residual Ca 2+ in the scale forming solution and interfere with the formation of calcite crystals.
Diethylenetriamine penta(methylene-phosphonic acid) (DTPMP) as a typical scale inhibitor is widely used in water treatment process because of its nontoxicity, low-cost, chemical stability, and strong chelating properties (Tantayakom et al. 2005). In virtue of the strong chelating property of the DTPMP molecule, DTPMP-metal ions films may be easily obtained through metal-organic coordination interaction (Kiaei and Haghtalab 2014). Notably, in the case of flame retardants, DTPMP molecule is rich in N and P elements and is expected to work well as an intumescent flame retardant during burning
The inhibition effect of diethylenetriamine penta(methylene phosphonic acid) (DTPMP) and Trisodium Citrate (TSC) on thecorrosion behavior of stainless steel in 0.5 M H2SO4 solution was investigated by using weight loss method. The combinedcorrosion inhibition efficiency offered 200 ppm of DTPMP and 150 ppm of TSC was 95%. Polarization study showed thatthe inhibitors inhibit stainless steel corrosion through mixed mode and electrochemical impedance spectroscopy (EIS)results confirm the adsorption of the inhibitors at stainless steel/acid interface. The adsorption of DTPMP and TSC ontothe stainless steel surface was found to follow Langmuir adsorption isotherm modes. Negative values of (ΔGads) in theacid media ensured the spontaneity of the adsorption process. The nature of the protective film formed on the metalsurface has been analyzed by FTIR spectra, SEM and AFM analysis. The activation energy (Ea), free energy change(ΔGads), enthalpy change (ΔHads) and entropy change (ΔSads) were calculated to understand the corrosion inhibitionmechanism.

DTPMP or diethylenetriamine penta(methylene phosphonic acid) is a phosphonic acid. It has chelating and anti corrosion properties.
Properties
DTPMP is normally delivered as salts, because the acid form has very limited solubility in water and tends to crystallize in concentrated aqueous solutions. It is a nitrogenous organic polyphosphonic acid. It shows very good inhibition of the precipitation of barium sulfate (BaSO4). At high alkali and high temperature (above 210 °C) environments DTPMPA has better scale and corrosion inhibition effect than other phosphonates.

Description: DTPMP or diethylenetriamine penta (methylene phosphonic acid) is a phosphonic acid. It has chelating and corrosion.
DTPMP is normally given as a salt because the acid form is soluble in water and tends to crystallize in concentrated aqueous solutions. It is an organic polyphosphonic acid with nitrogen. It inhibits the precipitation of barium sulfate (BaSO4) very well. DTPMPA has a better scale and rust inhibition effect compared to other phosphonates in high alkaline and high temperature (above 210 ° C) environments.
Uses: DTPMP is used in detergent and cleaning products, water treatment, scaling inhibition and chelation.
Toxicokinetic data on DTPMP and its salts are limited. The available information, together with data for phosphonic
acid compounds comprising Group 1 and Group2, suggest that only minor amounts of DTPMP and its salts would
enter the body after ingestion or skin contact.
The DTPMP acid and salts are of low oral and dermal toxicity. The oral rat LD50 is 4164 mg/kg bw and the rabbit LD50 is higher (>4605 mg/kg bw). The acute rat oral LD50 of the heptasodium salt lies between 5838 and 8757 mg/kg bw. The dermal LD50 values for the salts are >5838 mg/kg bw for the rat. For the octasodium salt, the oral LD50 is >3870 mg/kg bw and the dermal LD50 >860mg/kg bw for the rabbit. There is sufficient information from studies performed to an adequate standard, plus additional information from non-key studies, to support these values.There is evidence that DTPMP acid is an eye irritant, although different severities were reported in the two available assays (mild and severe). While both the formulations tested contained 10% HCl, which could contribute to the irritant response, it would however appear prudent to conclude that the anhydrous acid is a severe eye irritant. Evidence from three studies on DTPMP salts indicates these are only slightly irritating to the eye.Several studies on DTPMP acid and its salts indicate they have a low skin irritation potential. Although these studies tested formulations and therefore the limit dose for the active acid or salts was not achieved, the presence of hydrochloric acid in the formulations would be expected to exacerbate the response obtained. Therefore, in view of the very limited responses obtained, it is considered likely that the pure acid or salt, if tested to a limit dose, would be, at most, mild skin irritants.The salt of DTPMP has been studied in a good quality 90 day feeding study conforming to OECD guidelines. Repeated exposure to 842 mg/kg bw/d (males) and 903 mg/kg bw/d (females) resulted in perturbations of iron and calcium homeostasis (in the absence of any concurrent alteration of calcium plasma levels). Changes in some blood parameters and an increase in total bone density were seen at this dose. The NOAEL for this study was therefore 83 mg/kg bw/day based on the mid dose male group. There are a number of further studies available on the salt, covering durations from 90 days, one year or two years. In addition to effects on iron homeostasis and haematological effects, two of these studies have reported effects on liver pathology and NOAELs down to 4 mg/kg bw/d have been assigned. As these are secondary literature, where there is insufficient information for full evaluation, the findings are not considered to outweigh the recent GLP and OECD compliant 90 day study. Neither the acid nor the salt induces mutations in well-conducted studies in bacteria. The evidence for mutagenic potential in mammalian cells is conflicting. The acid, even when neutralized, can induce mutations at the thymidine kinase locus in mouse lymphoma L5178Y cells in the presence of S9 mix. A negative response was seen when the salt (neutralized with NaOH) was tested. The difference in outcome between the tests on the acid when neutralized with NaOH and on the salt is difficult to rationalize since the species tested should be similar for both test substances and similar dose ranges were tested. It is probable the positive response for the acid does not reflect an ability to interact with DNA due to (1) lack of structural alerts for mutagenicity, (2) lack of evidence for gene mutation potential in sub-mammalian systems and (3) lack of potential to induce gene mutations in another well-conducted assay investigating mutations at the hprt locus in CHO cells. Perturbations of pH and osmolarity are considered to be unlikely causes of the positive response due to the low concentration at which a positive response on the acid was seen (0.73 mM) and because positive responses are only seen consistently in the presence of S9. A plausible alternative explanation is the test substance interacts with S9 resulting in the formation of oxidative species. Evidence for a lack of mutagenic potential of DTPMP in vitro is supported by a negative hprt locus test and in vivo is provided by a well-conducted chromosome aberration study in rat bone marrow following gavage with doses up to 1970 mg/kg bw. Consequently DTPMP and its salt are not considered to pose a genotoxic hazard.
DTPMP is a polyphosphonic acid of molecular weight 573. The phosphonic acid function is a strong acid, and it is frequently produced as a salt for reasons of ease of use. It can form stable complexes with polyvalent metal ions. As a consequence of the ionisation over typical pH ranges, it is of high water solubility (≥ 500 g/l) and low octanol-water partition coefficient (Log Kow = -3.4). Its vapour pressure is very low (1.67 x 10-10 Pa (estimated)). At pH 7, DTPMP in water will be almost fully ionised five times, with a majority of the molecules ionised six times, and some seven or eight times. There is a possibility that the emission of a phosphonic acid could locally decrease the pH in the aquatic environment. In the normal use of these substances, their pH, concentration and water quality have to be monitored very carefully. Therefore, a significant decrease of the pH of the receiving water is not expected. Furthermore, the substances are usually used as salts with near-neutral pH, and their effects on pH are further buffered by the presence of metal ions. Generally the changes in pH of the receiving water should stay within the natural range of the pH, and for this reason, adverse effects on the aquatic environment are not expected due to release of the phosphonic acids. DTPMP and its salts may enter the environment via normal use in water treatment applications. It is predicted and has been shown to be adsorbed by inorganic matrices, and therefore adsorption to sewage sludge and soil is strong (measured Koc = 9748). They are not readily biodegradable in laboratory studies carried out under standard conditions. Although these data suggest the potential for persistence, there is, however, evidence of partial degradation by abiotic processes in natural waters, and biodegradation following acclimation, or under conditions of low inorganic phosphate. In the presence of commonly found metal ions possessing redox properties, such as iron, metal-catalysed photodegradation can be rapid, which promotes further biodegradation. DTPMP is not expected to be bioaccumulative, based on its low Log Kow and read-across from the two related substances ATMP and HEDP. As complexing agents, these substances could remobilise metals in the environment; however, their high degree of adsorption to sediments suggests that this is unlikely to occur. DTPMP and its salts are of low acute toxicity to fish and aquatic invertebrates. The lowest reliable acute toxic concentrations determined for DTPMP are a 96-h LC50 for the rainbow trout, Oncorhynchus mykiss, that is in the range 180-252 mg/l and EC50 values determined in acute tests with aquatic invertebrates are all in excess of 150 mg/l. DTPMP is of low chronic toxicity to fish (O. mykiss 60-day NOEC: 25.6 mg/l). There are no chronic data for aquatic invertebrates but an acute sub-lethal test with the oyster, Crassostrea virginica, yielded a 96-hour EC50 for effects on shell growth of 155.8 mg/l and a NOEC of 55.5 mg/l.
Current worldwide production of ATMP, HEDP and DTPMP (and their salts) is estimated to be in the range of 50,000 to 100,000 metric tonnes annually. The major uses of DTPMP and its salts are as an additive in water treatment, where its ability to both complex with metal ions, and to prevent crystalline scale deposition in solution and onto surfaces through adsorption, are utilised. The substances are also used in detergent and cleaning applications, and in the paper, textiles and photographic industries, and also in off-shore oil well applications. The major route of environmental exposure is expected to be release, often via wastewater treatment plants, to rivers. Agricultural land could be exposed via spreading of sewage sludge. Oil well use would lead to direct exposure of the marine environment. In rivers, they are expected to partition predominantly to sediment. Human exposure in manufacturing and formulating is possible, but due to the use of personal protective equipment, limited to accidental situation. Where exposure can occur, dermal exposure is the most likely route of exposure. In these cases PPE is recommended. The concentration of the substance in the product, together with PPE/engineering controls are important factors in the assessment of risk associated with the hazardous properties (mainly corrosivity/irritancy). Where concentrated solutions are handled, engineering controls and PPE are used to control exposure and reduce the risk from the corrosive/irritant properties. In downstream uses, where consumer exposure is possible, much more dilute concentrations are used, which significantly reduces or removes the likelihood of corrosivity/irritancy
