EDTA Use

This product is calcium complexing agent, a detergent, blood anticoagulant. Biochemical studies of calcium chelator used to eliminate traces of heavy metals enzymatic reactions resulting in inhibition.
EDTA is a good fit in the chemical agent, which is equipped with six atoms, the formation of complexes called chelates, EDTA titration is often used in the ligand, the metal ion content is generally measured in biological applications , to exclude most of the transition metal element ions (such as iron (III), Ni (II), Mn (II)) of the interference. Interfering ions can be removed without affecting the protein function in the case of protein engineering and testing.
EDTA is widely used, the color photographic materials can be used as a bleach-fixing processing, dyeing auxiliaries, fiber processing aids, additives, cosmetics, blood anticoagulants, detergents, stabilizers, synthetic rubber, a polymerization initiator, EDTA is a chelating Mixture of representative substances. Energy and alkali metal, rare earth elements and transition metals to form stable water-soluble complexes. Addition salt, there are various salts and ammonium salts of iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and the like. The main purposes: mainly used as a complexing agent ethylene diamine tetra-acetic acid, is widely used in water treatment, detergent additives, lighting, chemicals, paper chemicals, oil field chemicals, boiler cleaning agents and analytical reagents.
1, polymer chemistry industry: as styrene-butadiene latex polymerization activators, polymerization of acrylic fiber production plant terminator;
2, daily chemical industry: as a variety of detergents, skin care, hair perm additive agent;
3, the paper industry: fiber treatment agent used during cooking to enhance the whiteness of paper, reducing the steamer fouling;
4, the pharmaceutical industry: cyclization with formamide imine can be obtained, is a major drug for the treatment of psoriasis, but also as a stabilizer and certain vaccines blood anticoagulant;
5, textile printing and dyeing industry: improve the whiteness of hue and color dyes and dyeing textiles rate;
6, in the food industry: for chelating agent in canned food processing industry, get rid of the interference of metal ions.
7, in the molecular biology experiments: is a divalent metal chelating agent, inhibiting nuclease; decrease the stability of the cell membrane.
Furthermore, EDTA can also be used to make rapid excretion of harmful radioactive metal from the body play a role in detoxification.
