Disodium edetate dihydrate is a good compound in chemistry. It has important uses in dyes, food, medicine and other industries. It is tasteless, odorless or slightly salty white or milky white crystal or granular powder, odorless, tasteless. It is soluble in water and extremely difficult to dissolve in ethanol. It is an important chelating agent that can chelate metal ions in solution.
Industrial use: Ethylenediaminetetraacetic acid disodium salt is used for chemical copper plating, gold plating, lead tin alloy plating, electrochemical polishing of steel parts, and in the solution before silver plating of copper parts. It is also used in detergents, liquid soaps, shampoo, agricultural chemical sprays, bleaching fixer for color sensitive materials, water purification agent, pH regulator, retarder, etc.
Food additive: According to GB 2760-2014, disodium ethylenediaminetetraacetic acid can be used for jams, vegetable puree or sauce, preserved fruits, pickled vegetables, canned vegetables, canned nuts and seeds, canned miscellaneous grains, and compound seasonings, with maximum usage requirements.
Pharmaceutical use: Ethylenediaminetetraacetic acid disodium salt is approved by the FDA for the treatment of lead poisoning, by forming stable chelates with lead to help it be excreted from the body. In addition, it is also used in diagnostic tests to assess the lead levels in patients' bodies.
Cosmetic additives: Ethylenediaminetetraacetic acid disodium salt is used as a chelating agent in cosmetics, which helps to improve the stability and performance of the product.
Heavy metal analysis: In chemical analysis, ethylenediaminetetraacetic acid disodium salt is used as a quantitative analysis agent for heavy metals, which can chelate iron ions and control the polymerization reaction rate.
Environmental protection: In water treatment, disodium ethylenediaminetetraacetic acid can be used to remove heavy metal ions from water and reduce pollution.
