It is used in industries for water treatment, as a ceramic dispersant, a detergent material and a component for soil improvement. It is used in medical and electronics industries as an auxiliary infiltration agent.
Definition
ChEBI: A citrate salt in which all three carboxy groups are deprotonated and associated with ammonium ions as counter-cations.
Landwirtschaftliche Anwendung
Ammonium citrate is a white, granular, water-soluble salt of ammonia and citric acid. It 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 it to be better correlated with phosphorus uptake and plant growth. However, most countries use a neutral normal ammonium citrate solution for extracting citrate soluble phosphorus.
mögliche Exposition
It is used to make pharmaceuticals; rust-proofing compounds and plasticizers; as a food additive; stabilizing agent.
