Manufacture EDTA-2na Disodium Edetate Dihydrate C10h19n2nao9 CAS 6381-92-6
Product Description
Sodium salt of Ethylenediamine-N,N,N',N'-tetraacetic Acid (EDTA) a powerful chelating agent; EDTA forms stable complexes with most metal ions. EDTA is used in treatment of lead and heavy metal poisoning of farm animals.EDTA disodium (also known as EDTA disodium) is a strong chelating agent, because of its high stability constant and extensive coordination properties, almost with the alkali metal other than most metal ions (such as iron, copper, calcium, magnesium and other polyvalent ions) chelate to form a stable water-soluble complex, eliminate metal ions or harmful reactions caused by it.

Application
1.Among the salts of EDTA, the disodium salt is the most important and is an important complexing agent for complexing metal ions and separating metals, but also for detergents, liquid soaps, shampoos, agricultural chemical sprays, bleaching and fixing solutions for the development and processing of colour-sensitive materials, water purification agents, pH adjusters, anionic coagulants, etc. In the redox initiation system for the polymerization of styrene-butadiene rubber, disodium EDTA is used as a component of the active agent, mainly for complexing ferrous ions and controlling the rate of polymerization reaction. It is low toxic, with an oral LD50 of 2000 mg/kg in rats. Used as a chelating agent for metal ions.
2.Examines calcium, magnesium, etc. Used in pharmaceutical industry, colour development, smelting of rare metals, etc. It is an important complexing agent and metal masking agent.
3.Used as an carboxylate complexing agent for the determination of calcium, magnesium and other metals. Used as a metal masking agent and colour developer. Also used in the pharmaceutical industry and in the smelting of rare metals.
4.It is also used as an antioxidant synergist in cosmetics and is a metal ion chelating agent, which has the same effect as E DTA, but has a wider range of applications. It can be used in cosmetic raw materials containing trace metal ions and in the production and storage and transportation of cosmetics where metal containers are used.
