Application
1. Polymer chemical industry:
used as polymerization terminator for styrene-butadiene latex polymerization activator and acrylic fiber production device;
2. Daily chemical industry:
used as an additive for various detergents, skin care products and perm hair conditioners;
3, paper industry:
used as a treatment agent in fiber cooking, improve paper whiteness, reduce scaling in the steamer;
4, textile printing and dyeing industry:
to improve the dyeing rate and the color and whiteness of printing and dyeing textiles;
5, in the food industry:
can be used as a chelating agent in the food industry such as canning, to eliminate the interference of metal ions.
6. In molecular biology experiments:
it is a divalent metal chelating agent that inhibits nucleases; reduces the stability of cell membranes.
In addition, EDTA can also be used to detoxify harmful radioactive metals from the body.
