Application

1, EDTA is an important complexing agent, EDTA has a wide range of uses, can be used as colour photographic materials processing bleaching and fixing solution, dyeing auxiliaries, fibre processing aids, cosmetic additives, blood anticoagulant, detergent, stabilizers, synthetic rubber polymerization initiator, EDTA is a representative of the chelating agent. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are ammonium salt and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminium and other salts, these salts have different uses. In addition, EDTA can also be used to make harmful radioactive metals from the human body to play a detoxification role in rapid excretion. EDTA is also an important indicator, can be used to titrate the metal nickel, copper, etc., when used with ammonia, before Chemicalbook can play the role of indicator. 

2, EDTA is an excellent chelator of calcium and magnesium ions, used as a chelating agent for emulsion polymerisation of the water to remove Ca2+, Mg2+, Fe2+, Fe3+ and other metal ions. Metal ions. Also used as a complexing agent for anaerobic adhesives, that is, with EDTA treatment of methacrylic acid diester, to remove the transition metal ions, to eliminate the effects of peroxide decomposition can promote the stability of anaerobic adhesive is very good. sodium EDTA chelate metal ions can improve the modified acrylic acid fast. Solid structural adhesive (SGA) storage stability, dosage -3 × 10-4 ~ 6.0 × 10-4. dosage of 1.5%, 50 ~ C storage stability of more than 360h (50 ℃ storage 4d, equivalent to SGA20 ~ C storage for 1 year). 

3, commonly used in boiler water softening. Prevent scaling.
