The conjugate base of NTA is a tripodal tetradentate trianionic ligand, forming coordination compoundswith a variety of metal ions. Like EDTA, its sodium salt is used for water softening to remove Ca2+. For this purpose, NTA is a replacement for triphosphate, which once was widely used in detergents, and cleansers, but can cause eutrophicationof la...
In contrast to EDTA, NTA is easily biodegradable and is almost completely removed during wastewater treatment.The environmental impacts of NTA are minimal. Despite widespread use in cleaning products, the concentration in the water supply is too low to have a sizeable impact on human health or environmental quality.
