EDTA-4NA also known as ethylenediamine tetraacetic acid tetrasodium salt.

It is white powder. Easily soluble in water, the pH value of 1% aqueous solution is about 11.8, insoluble in alcohol, benzene, chloroform. Used as hard water softener, polyvalent chelating agent, bleaching fixing solution in color sensitive materials, activator of styrene butadiene rubber.

EDTA-4NA has complexing ability on calcium-containing hard water in various pH ranges and concentrations, and the highest power is reached at pH≥8. With calcium metal complex at 1∶1 molar ratio, in water heat stability is very good, even will not decompose in hot water , is a very useful hard water softener. Calcium ion complexing agent, scrubbing agent, blood anticoagulant. In biochemical research, it is used as a calcium chelating agent to eliminate the inhibition of enzyme catalyzed reactions caused by trace heavy metals.

EDTA-4na is an outstanding collaborator in chemistry, it has six coordination atoms, composed of coordination compounds called chelates, EDTA tetrasodium is often used in coordination titration, generally to determine the content of metal ions, in biological use, to eliminate most excessive metal element ions (such as iron (III), nickel (II), manganese (II)). In protein engineering and experiments, disturbing ions can be removed without affecting the function of proteins.

Edta-4na has a wide range of uses. It can be used as bleaching fixer for color sensitive materials scouring processing, dyeing aid, fiber treatment aid, cosmetic additive, blood anticoagulant, washing agent, stabilizer, synthetic rubber polymerization initiator. EDTA tetrasodium is a representative chelating agent. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium, there are ammonium salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts. Primary use: ethylenediamine tetraacetic acid is mainly used as complexing agent, widely used in water treatment agent, washing additives, lighting chemicals, papermaking chemicals, oilfield chemicals, boiler cleaning agent and analysis reagent.

Henan Zhenglin New Material Co., Ltd. mainly produces sodium tripolyphosphate, sodium hempetaphosphate, sodium dihydrogen phosphate, potassium dihydrogen phosphate, sodium gluconate, sodium acetate, polyacrylamide, polyaluminum chloride, phosphate and water treatment agents and other products are widely used in urban water supply, drainage, electric power, iron and steel, chemical industry, petroleum, paper, medicine, food and many other fields. Long committed to the development, production and application of industrial water treatment chemicals, to help customers resolve the conflict between water scarcity and growing demand.
