Chemical Property/Description:
Disodium edetate dihydrate(EDTA-2Na) is odorless or salty white or milky white crystalline or granular powder, odorless and tasteless. It is soluble in water and extremely insoluble in ethanol.
Main Uses:
EDTA-2Na (ethylenediaminetetraacetic acid disodium) is a highly efficient chelating agent, whose core function is to achieve multi field applications by chelating metal ions. Its main uses are classified as follows:
1, Industrial sector
-Metal processing and electroplating
Used in chemical copper plating, gold plating, and metal surface treatment solutions to prevent metal oxidation and improve coating uniformity.
-Textile printing and dyeing
As a dye stabilizer, it prevents dye decomposition and enhances dye adhesion.
-Water treatment
Chelate heavy metal ions (such as lead and mercury) and calcium and magnesium ions in water to reduce water hardness and prevent equipment scaling.
-Plastic and rubber
Serve as a plastic stabilizer and rubber antioxidant, delaying material aging.
2, Food industry
-Corrosion and color protection:
Prevent food discoloration and spoilage (such as soy sauce or canned food), inhibit vitamin C oxidation, and extend shelf life.
-Antioxidant enhancement:
Enhance the antioxidant properties of oils and reduce the impact of metal ion catalyzed oxidation.
3, Medical field
-Anticoagulants:
Chelate blood calcium ions to prevent specimen coagulation (purple blood collection tube).
-Detoxification of heavy metals:
Treat lead and mercury poisoning, form complexes to promote heavy metal excretion.
-Drug stabilizer:
Inhibit metal ion catalyzed drug degradation and prolong the effective period of injection.
4, Cosmetics
-Anti corrosion and Efficiency Enhancement: Enhance the antibacterial properties of the system and reduce microbial growth.
-Ingredient protection: prevent active ingredients (such as VC) from being oxidized and rendered ineffective by metal ions.
5, Agricultural applications
-Micro fertilizer carrier: chelates with trace elements to enhance plant absorption efficiency.
-Soil remediation: passivate soil heavy metals and reduce crop toxicity.
6, Research and Laboratory
-DNA extraction/PCR: Inhibits metal dependent nuclease activity to ensure experimental accuracy.
-Electrophoretic buffer: maintains electric field stability.
