Use of ethylenediaminetetraacetic acid disodium dihydrate
EDTA-2K, EDTA-3K, EDTA-2Na are commonly used in the EDTA series products we know. Among them, EDTA disodium products are widely used. As the most important chelating agent in the industry, EDTA can be used as heavy metal antidote, complexing agent, antioxidant synergist, stabilizer and softener, etc.; calcium, magnesium and others Metal reagents, metal masking agents. Disodium ethylenediaminetetraacetic acid is an important complexing agent used to complex metal ions and separate metals. Commonly used in daily chemicals and cleaning!

Ethylenediaminetetraacetic acid disodium dihydrate, also known as disodium EDTA, CAS number is 6381-92-6, molecular formula is C10H14N2O8Na2·2H2O, appearance is white crystalline powder, it is odorless, tasteless, soluble in water, Very difficult to dissolve in ethanol.
EDTA-2Na can cause irritation to mucous membranes, upper respiratory tract, eyes and skin. In addition, EDTA-2Na can also combine with calcium ions to form a soluble complex. If EDTA-2Na is used in violation of regulations or in excess, it will affect the body. Being healthy can cause symptoms such as vomiting, diarrhea, and acute abdominal pain. It may also lead to the loss of trace elements in the human body, such as reducing the blood calcium concentration and causing hypocalcemia.
Ethylenediaminetetraacetic acid disodium dihydrate has six coordinating atoms and two crystal water. It is an excellent chelating agent. It has a strong ability to complex a variety of metal ions and separate metals. It can be used as a color photosensitive material Bleaching and fixing liquids and dyeing auxiliaries for processing, fiber treatment agents, cosmetic additives, medicine, food, agricultural chemical fertilizer production, blood anticoagulants, water softeners in detergents, stabilizers, synthetic rubber, polymerization initiators and Heavy metal quantitative analysis agent, etc. Specific application examples are as follows:
1. Ethylenediaminetetraacetic acid disodium dihydrate as a complexing agent: used to soften hard water and effectively complex a variety of metal ions in hard water, such as calcium, magnesium and iron, lead, copper, manganese, etc.; in washing Auxiliaries and photosensitive chemicals play a great role, which can enhance the cleaning power, foaming power, penetration power and emulsifying power of the detergent, and can also control the concentration of ferric ions in the bleaching solution, prevent the generation of precipitation, and improve Washing quality
2. Ethylenediaminetetraacetic acid disodium dihydrate as a reference reagent: used for chemical analysis in all walks of life. It is the top priority of chemical analysis standard solutions and an indispensable working variable reference substance in analysis and testing.
3. Ethylenediaminetetraacetic acid disodium dihydrate as a stabilizer: used in pharmaceutical injections, can effectively enhance the stability of the drug, the principle is that disodium edetate can form a stable water-soluble chelate with metal ions It can prevent self-oxidation, which is beneficial to improve the stability of the drug in the process of preparation, storage and clinical preparation.
