EDTA Tetra Sodium Salt

Tetrasodium 2,2′,2′′,2′′′-(Ethane-1,2-diyldinitrilo)tetraacetate. EDTA 4Na is the tetrasodium tetrahydrate salt of the well-known chelating agent. It is highly effective at low concentrations at a very wide acidic and alkaline pH range.

Tetrasodium EDTA is a solid, colorless, and water-soluble amino polycarboxylic acid that is used in various industries and is mostly used as a chelator and inactivates them by binding to specific mineral ions.

Tetrasodium EDTA Uses:

Tetrasodium EDTA is mostly used in the production of detergents. Water and wastewater treatment and the paper industry are in the next categories.

Industrial Detergents:

Hard water is the main challenge of detergents in the cleaning process. Hard water is water that has high amounts of metal ions and ionic compounds. Detergents normally react with these metal ions and ionic compounds in water and lose their properties. The purpose of using EDTA is quite simple; Prevent the presence of minerals in the water from the reaction with detergents and thus perform a perfect cleaning process even in hard water.

Water Treatment:

Water and sewage pollution from industrial and domestic activities has become a serious problem. Advances in industries such as mining, steel, and metal plating have allowed water contaminated with harmful metals to enter nature. These dangerous elements enter the human food chain through direct drinking of polluted water or through plants and animals, causing irreversible effects on the human body. For this reason, the use of chelating compounds, led by Tetrasodium EDTA, has received more and more attention. EDTA 4Na is widely used in water and wastewater treatment due to its abundance and cost-effectiveness. This compound can absorb and neutralize metal ions such as lead, cadmium, mercury, and cobalt. The combination of EDTA and metal ions is then removed from the water by methods such as reverse osmosis, and the purified water returns to nature or the cycle of use.

Paper Industry:

EDTA contributes to the whiteness and luminosity of paper by combining it with metal ions to catalyze the decomposition of hydrogen peroxide in the paper-making process. This compound also blends with wood lignin in pulp to give the paste a shiny, white appearance.
