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:

EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.
