Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca ...

EDTA or e thylene d iamine t etra a cetic acid is a novel molecule for complexing metal ions. It is a polyprotic acid containing four carboxylic acid groups (acidic hydrogens are red) and two amine groups with lone pair electrons (green dots). The classic structural formula is given below.

2025年1月27日 · Ethylenediamine-N,N,N’N’tetraacetic Acid (EDTA) is a powerful chelating agent; EDTA forms stable complexes with most metal ions. EDTA is used in treatment of lead and heavy metal poisoning of farm a nimals.

2024年7月20日 · What is Ethylenediaminetetraacetic Acid? Ethylenediaminetetraacetic acid, better known as EDTA, is an aminopolycarboxylic acid with the formula C 10 H 16 N 2 O 8. It is a white solid that is insoluble in water and is one of the most commonly used chelating agents in diverse industries.

EDTA refers to the chelating agent with the formula (HO 2 CCH 2) 2 NCH 2 CH 2 N (CH 2 CO 2 H) 2. This amino acid is widely used to sequester di- and trivalent metal ions. EDTA binds to metals via four carboxylate and two amine groups. EDTA forms especially strong complexes with Mn (II), Cu (II), Fe (III), and Co (III). [1]

EDTA forms coordination complexes with metal ions. It has 6 lone pairs of electrons (two nitrogen atoms and four oxygen atoms) which can participate in formation of coordinate bonding with metal ions (hexadendate ligand). Most applications of EDTA rely on its ability to chelate metal ions.
