overview | there are two kinds of existing trace element fertilizers, one is sulfate, such as FeSO4.CuSO4.MnSO4.ZnSO4.MgSO4, the other is sulfate EDTA • 2Na (stabilizer urea), the existing sulfate EDTA • 2Na (stabilizer urea) preparation method is: sulfate FeSO4.CuSO4.MnSO4.ZnSO4.MgSO4 is completely dissolved in water within 70 ℃ to obtain solution a, EDTA 2Na is completely dissolved in water within 70 ℃ to obtain solution B, the solutions a and B are mixed and stirred according to the ratio of EDTA 2Na: sulfate: water (molar ratio) = 1: 0.1-0.5: 300-2500 for 0.5 hours, the pH value is adjusted with NaOH, and the finished product is obtained by filtration. There are many shortcomings in this production method. Disodium manganese ethylenediaminetetraacetic acid is one of the complex metal salts of ethylenediaminetetraacetic acid. |
properties | micropink red powder, easily soluble in water, manganese exists in chelated state. |
use | as a trace element nutrient agent, used in agriculture. Metal chelating compound Used to eliminate the inhibition of enzyme-catalyzed reactions caused by trace heavy metals |
