China Manufacturer for Polyaluminium Chloride For Waste Water - Edetate disodium – Bohua Detail:
Ethylenediamine tetraacetic acid disodium is also known as edta-2na, is a good coordination agent in chemistry, it has six coordination atoms, the formation of complex is called chelate, EDTA is often used in coordination titration, generally is to determine the content of metal ions. EDTA has important applications in dyestuff, food, medicine and other industries.
Disodium ethylenediamine tetraacetic acid is a white crystalline particle or powder, odorless and tasteless. It is soluble in water, but extremely difficult in ethanol. It is an important integrator and can bind metal ions in solution. Prevent metal caused by discoloration, deterioration, turbidity and vitamin C oxidation loss, but also can improve the antioxidant oil (oil trace metals such as iron, copper and so on have the role of promoting oil oxidation).
