Description
1. Edetic Acid Introduction
EDTA Acid is anaminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-soluble solid is widely used to bind to iron (Fe2Fe3+) and calcium ions (Ca2+). It binds these ions as a hexadentate (“six-toothed”) chelating agent. EDTA is produced as several salts, notably disodium EDTA, sodium calcium edetate, and tetrasodium EDTA.
