DTPA Chelating Agent for Water Treatment
Diethylenetriaminepentaacetic acid (DTPA) is a powerful pentadentate chelating agent that forms stronger and more stable metal complexes than EDTA, particularly with iron, manganese, and heavy metals. It is widely used in industrial water treatment, pulp bleaching, and hydrogen peroxide stabilization. DTPA is preferred over EDTA in systems with elevated transition metal ion concentrations.
