Application
EDTA is widely used. It can be used as a bleaching fixative for color sensitive materials, dyeing auxiliaries, fiber processing aids, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber initiators, and EDTA is a representative material of chelating agents.
1. Textile printing and dyeing industry: improve the color rate of dye and color and whiteness of textile.
2. Food industry: a chelating agent can be used in the food industry, such as canning, to remove the interference of metal ions.
3. The molecular biology experiment: it is a two valence metal chelating agent that inhibits the nuclease, and reduces the stability of the cell membrane.
4.In addition, EDTA can also be used to excrete harmful radioactive metals from the human body to detoxify.
