Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) is an organic compound with the chemical formula C10H16N2O8. It is a white powder at room temperature and pressure. It is a substance that can react with Mg2+ A chelating agent that combines divalent metal ions such as Ca2+, Mn2+, and Fe2+.
EDTA is an important chelating agent. EDTA has a wide range of applications and can be used as a bleaching and fixing solution for the processing of color sensitive materials, dyeing aids, cosmetic additives, stabilizers, and synthetic rubber polymerization initiators, EDTA is a representative substance of chelating agents. It can form stable water-soluble complexes with alkali metals, rare earth elements, and transition metals. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc., each with different uses.
In addition, EDTA can also be used to quickly excrete harmful radioactive metals from the human body and play a detoxifying role. It is also a water treatment agent.
EDTA is also an important indicator, but it is used to titrate metals such as nickel and copper. When used, it must be used together with ammonia to act as an indicator.
