Iron Compounds

Ferrous Sulfate Heptahydrate

Used as an analytical reagent and raw material for ferrite; as an iron enhancer for feed additives. In agriculture, it can be used as a pesticide to prevent wheat smut, scab of apples and pears, and rot of fruit trees; it can also be used as a fertilizer to remove moss and lichen from tree trunks. It is a raw material for manufacturing magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalysts and polyferric sulfate. Used in medicine as a local astringent and blood tonic. It is also used as a chromatographic analysis reagent. Food grade is used as a nutritional supplement, such as iron fortifier, fruit and vegetable coloring agent. Feed grade ferrous sulfate, used as an iron supplement in feed processing. Used as food iron fortifier. China stipulates that it can be used for filling sugar and table salt, and the usage amount is 3000~6000mg/kg; in high-iron cereals and their products (daily limit of 50g of such foods), it is 860~960mg/kg; in dairy products and infant food It is 300-500mg/kg; in cereals and its products, it is 120-140mg/kg; in beverages, it is 50-100mg/kg.
