Fe-TAML: Catalyst for Cleanup Valerie J. Brown Abstract Estrogens in contraceptives and hormone replacement therapy, those given to agricultural animals, and industrial chemicals that mimic estrogen add to the volume of naturally occurring biologically active compounds in the environment. These compounds make their way into surface and groundwater, and eventually into drinking water supplies, where they have been shown to cause adverse developmental effects in animals. U.S. wastewater plants are not currently required to remove these substances, though eventually they may be. Now scientists are experimenting with catalysts called Fe-TAML® (iron plus tetra-amido macrocyclic ligand) activators as an effective, nontoxic approach to removing these and other contaminants from wastewater.
