Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-insoluble solid is widely used to bind to iron (Fe /Fe ) and calcium ions (Ca ), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale … See more Textile industry In industry, EDTA is mainly used to sequester (bind or confine) metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colours … See more The compound was first described in 1935 by Ferdinand Münz, who prepared the compound from ethylenediamine and chloroacetic acid. … See more In coordination chemistry, EDTA is a member of the aminopolycarboxylic acid family of ligands. EDTA usually binds to a metal cation through its two amines and four carboxylates, … See more Interest in environmental safety has raised concerns about biodegradability of aminopolycarboxylates such as EDTA. These concerns incentivize the investigation of alternative aminopolycarboxylates. Candidate chelating agents … See more EDTA exhibits low acute toxicity with LD50 (rat) of 2.0 g/kg to 2.2 g/kg. It has been found to be both cytotoxic and weakly genotoxic in … See more To describe EDTA and its various protonated forms, chemists distinguish between EDTA , the conjugate base that is the ligand, and H4EDTA, the precursor to that ligand. At very … See more Abiotic degradation EDTA is in such widespread use that questions have been raised whether it is a persistent organic pollutant. While EDTA serves many … See more WebEthylenediamine tetraacetic acid, EDTA. Ethylenediamine tetraacetic acid is widely used as a complexing agent because of its strong complexing ability with metal cations. The EDTA can draw out metals from exchange sites of both organic and inorganic groups, and dissolve calcareous deposits through its complexation with metal ions or Ca 2+ and ...
