Ethylenediaminetetraacetic acid (EDTA)
Industrial Applications
Ethylenediaminetetraacetic acid (EDTA) is a versatile chelating agent widely used across multiple industries. It binds metal ions such as Fe²⁺, Fe³⁺, and Ca²⁺, forming water-soluble complexes. In water treatment and cleaning, Ethylenediaminetetraacetic acid dissolves Fe- and Ca-containing scale and prevents metal ion interference. In pharmaceuticals, Ethylenediaminetetraacetic acid binds with toxic metal ions for safe drug delivery. Ethylenediaminetetraacetic acid salts, including disodium EDTA, sodium calcium edetate, and tetrasodium EDTA, are used in cosmetics, detergents, and industrial processes to improve stability, prevent precipitation, and enhance product performance.
Physical Properties
Ethylenediaminetetraacetic acid is an aminopolycarboxylic acid, typically available as a white, odorless, crystalline powder. It is insoluble in pure water but forms highly soluble complexes with metal ions. Ethylenediaminetetraacetic acid is thermally stable under normal conditions and chemically stable at neutral pH. Its solid form is non-volatile and easily handled in powders or salts for industrial, laboratory, and pharmaceutical applications.
