Ethylenediaminetetraacetic Acid (EDTA)
Versatile Chelating Agent for Industrial and Commercial Applications
Ethylenediaminetetraacetic acid (EDTA), is a white crystalline powder with weak acidity. As a hexadentate ligand containing four carboxyl groups and two amine groups, EDTA demonstrates exceptional metal-chelating capabilities. It exhibits low solubility in cold water (0.5 g/L at 20°C) but significantly higher solubility in alkaline solutions. The compound shows limited solubility in common organic solvents while maintaining stability under routine storage conditions.
EDTA's unique molecular structure enables the formation of stable coordination compounds with most di- and trivalent metal ions through six binding sites. This chelation mechanism allows effective sequestration of metal ions even in trace concentrations. The compound demonstrates pH-dependent behavior, with optimal chelation occurring in alkaline environments.
Key industrial applications include:
·Water Treatment: Scale inhibition and metal ion removal in boiler systems/cooling towers
·Food Industry: Preservation agent (E385) for color retention and oxidation prevention
·Pharmaceuticals: Active ingredient in anticoagulant drugs (e.g., EDTA dipotassium in blood collection tubes)
·Cosmetics: Stabilizer in formulations by neutralizing metal-induced degradation
·Industrial Cleaning: Key component in metal surface treatment and decontamination solutions
·Agriculture: Micronutrient carrier in fertilizer formulations
