2.Application of EDTA:
As an agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent,
a chemical for photography, paper-making and oil-field.
It is also used as detergent for boiler cleaning and reagent in chemical analysis.
1) High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production.
2) Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner.
3) Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer.
4) Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin.
5) Textile dyeing and printing
