EDTA Acid

EDTA (Ethylenediaminetetraacetic acid) is a versatile chelating agent that binds strongly to divalent and polyvalent metal ions, including calcium, magnesium, and lead. It is widely used as a lead chelator in cases of heavy metal poisoning and as an anticoagulant in blood collection by sequestering calcium ions, which are essential for clotting. EDTA’s mechanism involves the formation of stable, water-soluble complexes with metal ions, effectively reducing their biological availability and reactivity.
