　　EDTA is an important chelating agent. EDTA has a wide range of applications and can be used as a bleaching and fixing solution for color photosensitive materials, a dyeing aid, a fiber processing aid, a cosmetic additive, a blood anticoagulant, a detergent, a stabilizer, and a synthetic rubber polymerization initiator. EDTA is a representative substance of chelating agents. Can form stable water-soluble complexes with alkali metals, rare earth elements, transition metals, etc. In addition to sodium salts, there are also ammonium salts and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc. These salts have different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body. It is also a water treatment agent. EDTA is still an important indicator, but when used to titrate metals such as nickel and copper, it must be used together to function as an indicator.
