Product details
Ferrous Sulfate: Alias: ferrous iron, ferrous sulfate heptahydrate, green alum, drying type ferrous sulfate, the use can be used as electroplating plant as a reducing agent, industrial wastewater flocculant, printing and dyeing plant to do the precipitant, as raw materials for the iron-red plant, as raw materials for pesticide factories, as raw materials for fertilizer factories, ferrous sulfate fertilizer in flowers and so on.
Widely used in printing and dyeing, papermaking, sewage, industrial wastewater flocculation clarification and decolorization, ferrous sulfate can also be used to deal with chromium-containing wastewater and cadmium-containing wastewater. Ferrous sulfate can also be used to treat chromium-containing wastewater and cadmium-containing wastewater, such as high alkalinity, high chroma wastewater treatment, which can reduce the large amount of inputs of neutralizing acid.
Uses of Ferrous Sulphate Monohydrate.
It can be used as a pesticide in agriculture to prevent and control the black spike disease of wheat, scab disease of apple and pear, and rot disease of fruit trees; it can also be used as a fertilizer to remove the moss and lichen from the trunk of trees. It is the raw material for manufacturing magnetic iron oxide, iron oxide red and iron blue inorganic pigment, iron catalyst and ferric sulfate. In medicine, it is used as local astringent and blood tonic.
It is also used as a reagent for chromatographic analysis. Edible grade is used as nutritional supplements, such as iron fortifier, fruit and vegetable coloring agent. Feed grade ferrous sulfate is used as iron supplement in feed processing.
Role of Ferrous Sulphate Monohydrate.
Ferrous sulfate has many functions, it can be used as plant fertilizer, adjust the acidity and alkalinity of soil, increase the iron content suddenly, etc. It is used more in agricultural production and daily flower raising.
Ferrous sulfate is also the raw material for industrial production of iron salts, and can also be used for industrial wastewater treatment and sewage treatment in many industries, in the treatment of urban sewage, ferrous sulfate has a strong effect of phosphorus removal and so on. High-quality ferrous sulfate is also used in food additives and pharmaceutical production, can improve anemia, but need to have medical advice to take.
Product Method of Bulk Ferrous Sulphate Monohydrate Powder.
(1) Production of titanium dioxide by-product method. When ilmenite is decomposed with sulfuric acid to make titanium dioxide, ferrous sulfate and iron sulfate are generated, and the trivalent iron is reduced to divalent iron with iron wire. The by-product ferrous sulfate can be obtained by freeze crystallization.
(2) sulfuric acid method. Dissolve the iron filings in a mixture of dilute sulfuric acid and mother liquor, control the reaction temperature below 80 ℃, otherwise ferrous sulfate monohydrate precipitation will be precipitated. The slightly acidic ferrous sulfate solution generated by the reaction is clarified to remove impurities, then cooled and centrifuged to obtain light green ferrous sulfate.
