Ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA) are synthetic complexing agents that have been utilized extensively as metal sequestrants by a wide variety of industries. EDTA has been used mainly as a chelating agent, e.g., in the metal, rubber, leather, photographic, textile, pulp and paper, pharmaceutic, cosmetic, and food industries. Applications of DTPA include the inactivation of metal ions in the pulp and paper industry and use as a drug in heavy metal poisoning. The chemical structures of EDTA and DTPA are shown in Fig. 1.
