The Uses Of EDTA-4Na In Industrial Field

‌ Ethylenediaminetetraaceticacid tetrasodium salt,also called EDTA tetrasodium ‌ (EDTA-4NA) is an important chemical with a wide range of applications. It is a white crystalline powder, soluble in water, odorless and tasteless, and is a strong chelating agent. EDTA tetrasodium has the chemical formula C10H12N2Na4O8 and is soluble in water and acid, but insoluble in alcohol, benzene and trichloromethane. It can interact with a variety of metal ions to form chelates, so it is widely used in many fields.

EDTA 4na 

‌EDTA-4Na is widely used in industry, including but not limited to water treatment agent, detergent additive, color photosensitive material washing processing bleaching fixing solution, water purification agent, PH regulator, coagulant and so on.

‌Water treatment agent:

EDTA-4Na, as an important complexing agent and metal masking agent, is widely used in industry and life. It can be combined with heavy metal ions in water, thereby softening the water quality, removing metal ions and hard substances in water, and protecting certain sensitive metals from corrosion.

‌Detergent additive :

In detergent, liquid soap, shampoo and other daily chemicals, EDTA-4Na as an additive, can enhance the cleaning ability of detergent, by combining with metal ions, reduce the oxidation and deterioration of metal ions on food, so as to prevent food deterioration and spoilage.

‌Bleaching fixing solution for color sensitive materials:

During the rinsed processing of color sensitive materials, EDTA-4Na is used in the bleaching fixing solution to help remove the unnecessary part on the image material and ensure the clarity of the image.

‌Water purifier and PH regulator:

In the environmental protection industry, EDTA-4Na is also used to treat industrial wastewater and domestic sewage to help remove heavy metal ions and harmful substances from water, and can also be used as a PH regulator to regulate the pH of water to make it more compliant with discharge standards.

‌Anticoagulant:

In addition, EDTA-4Na is also used to prevent or reduce the occurrence of some chemical reactions, such as in the reduction initiation system for styrene butadiene rubber polymerization, EDTA tetrafodium as a component of the active agent, is mainly used for complexing ferrous ions, control the polymerization reaction speed, thus affecting the quality and performance of products.

In summary, the application of EDTA-4Na in industry is not limited to the above aspects, but also plays an important role in other fields, and is a multi-functional chemical reagent.
