In the salts of ethylenediamine tetra acetic acid, two sodium salt is the most important. It is an important complexing agent. It is used for complexing metal ions and separating metals. It can also be used in detergents, liquid soap, shampoo, agricultural chemical spray, color photosensitive material, rinsing and processing bleaching fixative, water purifying agent, pH regulator, negative coagulant, etc. In the redox initiation system for SBR polymerization, EDTA disodium is used as an active agent to complex ferrous ions and control the polymerization reaction rate. The drug is low toxicity, and LD50 is 2000 mg / kg in rats. Used as a chelator for metal ions.
Check calcium, magnesium, etc. It is used in pharmaceutical industry, color development, smelting of rare metals and other fields. It is an important complexing agent and metal masking agent.
It is used as ammonia carboxycomplex for the determination of calcium, magnesium and other metals. It is used as metal masking agent and color developer. It is also used in pharmaceutical industry and smelting of rare metals.
It is also used as an antioxidant and a metal chelating agent, which has the same function as e DTA, but it has a wider application range. The cosmetics raw materials contain trace metal ions and can be used in the production and storage and transportation of cosmetics.
Keep away from light, in a cool and dry place, sealed.
