Ethylenediaminetetraacetic acid
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid after its own abbreviation, is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe2+/Fe3+) and calcium ions (Ca2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale as well as to deliver iron ions under conditions where its oxides are insoluble. EDTA is available as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA, but these all function similarly.
Ethylenediaminetetraacetic Acid is known for its ability to form stable complexes with metal ions, effectively sequestering them in solution. This property makes EDTA valuable in applications where control of metal ion concentrations is crucial. EDTA is also a common ingredient in various formulations across different industries, including cosmetics, food, and pharmaceuticals.
