EDTA, white odorless, tasteless, colorless crystalline powder, melting point 250 ℃ (decomposition). Insoluble in alcohol and general organic solvents, soluble in cold water (cold water speed is slow), hot water, soluble in sodium hydroxide, sodium carbonate and ammonia solutions, soluble in 160 parts of 100 ℃ boiling water. Its alkali metal salts can be dissolved in water. EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixing solution for the washing and processing of color photosensitive materials, dyeing additives, fiber treatment additives, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators. EDTA is a representative substance of chelating agents. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are ammonium salt and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt and aluminum. These salts have different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body to detoxify. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel and copper. When it is used, it should be used together with ammonia to play the role of indicator. EDTA is mainly used in agriculture to produce micro fertilizers of iron, zinc, manganese, copper and other elements or to prepare plant growth promoters.
Characteristics of EDTA
Improve the viability of pollen, promote the development of crop reproductive organs, and prevent fruit drop and stiff fruit; Enhance crop stress resistance, improve quality and increase yield.
Good compatibility, can be mixed with most pesticides, and can effectively improve the efficacy of pesticides.
Providing rich comprehensive and balanced trace elements nutrition for plants and soil. Improving the plants’ absorption for trace elements, to increase the plant growth, fruits and increase the yield.
Enhancing the absorption of chemical fertilizer. Keeping the water and nutrition of the soil. And green and environmental-friendly.
