Application:

1. Ferrous sulfate heptahydrate is used as a local astringent and blood tonic in medicine. In addition, it is also used as chromatographic analysis reagent.

2. Ferrous sulfate heptwater is used as nutritional supplement for food grade, such as iron fortifier, fruit and vegetable hair color agent. Feed grade ferrous sulphate is used as iron supplement in feed processing.

3. When used as an iron fortifier for food. According to the regulations of China, it can be used for bonbon and salt, with the usage amount being 3000 ~ 6000mg/kg. 860 ~ 960mg/kg of high iron cereals and their products (50g/Chemicalbook day limit); 300-500mg/kg in dairy products and infant food; 120~140mg/kg in cereals and their products; 50~100mg/kg in beverages.

4. It is also used to make iron salts, iron oxide pigments, mordants, water purifiers, preservatives, disinfectants, medicine as an anti-anemia drugs.

Production method:

(1) Production of titanium dioxide by-product method. When titanium dioxide is produced by the decomposition of ilmenite with sulfuric acid, ferrous sulphate and ferrous sulphate are formed, and ferric trivalent iron is reduced to ferric divalent iron with iron wire. The by-product of ferrous sulfate can be obtained by freezing crystallization.

(2) Sulfuric acid method. The iron chip is dissolved in the mixture of dilute sulfuric acid and mother liquor, and the reaction temperature is controlled below 80℃, otherwise the precipitation of ferrous sulfate monohydrate will occur. The slightly acidic ferrous sulphate solution obtained by the reaction was clarified, the impurities were removed, then cooled and centrifuged to obtain pale green ferrous sulphate.
