Agricultural Uses
E380 Triammonium citrate is a white, granular, water-soluble salt of ammonia and citric acid.
E380 Triammonium citrate is used in a neutral solution for determining the phosphorus content of phosphate fertilizers (such as calcium hydrogen phosphate (CaHPO4)), that are insoluble in water but dissolve in complexing citrate solutions.
The fertilizer residue, after extraction of watersoluble phosphorus, is re-extracted with a neutral or strongly alkaline solution of 1 normal (1N) ammonium citrate for a prescribed period, and the slurry filtered.
Citrate-soluble phosphorus is the phosphorus content in the filtrate and is expressed as a percentage by weight of the fertilizer.
The extraction of phosphate with 1N ammonium citrate is carried out routinely for 30 minutes, first at room temperature and then at 4O℃ For neutral ammonium citrate solution, a temperature of 65℃ is preferred.
Some European countries use an alkaline ammonium citrate solution, which extracts smaller amounts of phosphorus.
Some experts consider E380 Triammonium citrate to be better correlated with phosphorus uptake and plant growth.
However, most countries use a neutral normal E380 Triammonium citrate solution for extracting citrate soluble phosphorus.
Industrial uses
E380 Triammonium citrate can serve as an effective leaching agent for extracting lead from lead oxide ore.
E380 Triammonium citrate has been reported that, under conditions of 800 r/min and 40°C, leaching with a 1.25 mol/L solution of E380 Triammonium citrate for 21 minutes can extract approximately 95% of the lead content from samples with a particle size range of +75 to 96 μm.
