Production method

1. Its production methods are ferric nitrate method and ferric chloride method. Ferric nitrate method added ferric nitrate into the reactor containing distilled water, slowly added anhydrous sodium pyrophosphate under stirring for reaction, to produce ferric pyrophosphate, added arsenic and heavy metal removal agent for solution purification, filtration to remove arsenic and heavy metals and other impurities, quickly added the newly prepared polyacrylamide aqueous solution to the filtrate, after static pouring out the superwhite, slurry filtration, wash with hot water Finally, it is washed with methanol and dried at 80 ~ 90℃ to produce edible iron pyrophosphate products

2. Sodium pyrophosphate aqueous solution is added to ferric chloride or citric acid hot metal solution, and the precipitation generated is filtered and washed, and then dried and crushed.

3. The production method has two kinds of ferric nitrate method and ferric chloride method. Ferric nitrate process The ferric nitrate is added to the reactor containing distilled water, and the anhydrous sodium pyrophosphate is slowly added to the reaction under stirring to produce iron pyrophosphate. The solution is purified by adding arsenic and heavy metal removal agents, and the impurities such as arsenic and heavy metals are removed by filtration. The newly prepared polyacrylamide aqueous solution is quickly added to the filtrate, and the superwhite is poured out after static treatment, and the slurry is filtered, washed with hot water, and finally Then wash with methanol and dry at 80 ~ 90℃ to produce edible iron pyrophosphate products, the reaction formula is as follows.

Use

Nutrient supplement (iron fortification agent).
