China EDTA Chemical Supplier & Manufacturer

EDTA

Ethylenediamine tetraacetic acid (EDTA) is an organic compound with the chemical formula C10H16N2O8 and is a white powder at room temperature and pressure. It is a chelating agent that can bind with Mg2+, Ca2+, Mn2+, Fe2+ and other bivalent metal ions. Mg2+ is often used as an inhibitor of nucleases and proteases because most nucleases and some protein enzymes require Mg2+. It can also be used to remove the inhibition of heavy metal ions on enzymes.

Applications of EDTA

1. EDTA is an important complexing agent.

2. EDTA is widely used, can be used as color photosensitive material washing processing bleaching fixing solution, dyeing AIDS, fiber treatment AIDS, cosmetic additives, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator.

3. EDTA is a representative of chelating agent. It can form stable water-soluble complexes with alkaline earth metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, which have different uses. In addition.

4. EDTA can also be used to make harmful radioactive metals quickly excreted from the body to play a detoxification role. It's also a water treatment agent.

5. EDTA is also an important indicator, but used to titrate metal nickel, copper, etc., when used with ammonia, in order to play the role of indicator.
