EDTA is an important chelating agent with wide application. It can be used in detergents, dyeing adjuvant, processing agent for fibers, cosmetic additive, food additive, blood anticoagulants, water treatment agent and agriculture fertilizers, etc.
EDTA can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, which have different uses.
In addition, EDTA can also be used to detoxify harmful radioactive metals rapidly excreted from the human body.
