Product overview

Ethylenediamine tetraacetic acid disodium, also known as EDTA-2Na, is a good compound in chemistry.

The chemical formula is C10H14N2Na2O8, and the molecular weight is 336.206.

It has six coordination atoms, and the complex formed is called chelate.

EDTA is often used in coordination titration, which is generally used to determine the content of metal ions.

EDTA has important uses in dye, food, medicine and other industries.

Applications

Industrial grade use of EDTA 2NA

① Industry: clean up heavy metal ions and Ca2+ and Mg2+ ions.

② Soap: combine with Ca2+ and Mg2+ ions in hard water to reduce hardness.

③ Photography: Fe(III)EDTA was used as oxidant.

④ Textiles: combined with heavy metals.

⑤ Oil production: EDTA is added to prevent mineral precipitation.

⑥ Milk: wash the milk bottle.

⑦ Nitrogen oxides: exhaust gas treatment.

Food grade use of EDTA 2NA

The purity of food grade EDTA must be above 99%.
