Divided by the water content of ferrous sulfate, a water and seven water; use is divided into agricultural, industrial, pharmaceutical, food-grade and so on. Ferrous sulfate heptahydrate (Green Fan) for the manufacture of iron pigments, iron-based catalyst and water purification, sewage treatment, etc.; ferrous sulfate monohydrate mainly as feed additives. Appearance: a ferrous sulfate monohydrate is yellowish powdery appearance, size :70-100 mesh 100-200 mesh 200-300 mesh two ferrous sulfate heptahydrate appearance is green, light green powder granular Specification: 70 -. 100 mesh Moisture: 0.5% ferrous sulfate chemicals Chinese name: English name of the chemical ferrous sulfate: ferrous sulfate Chinese name 2: green vitriol Name 2: green vitriol Technical Manual Code: 2536 CAS No:. 7782-63-0 MF: FeSO47H2O ferrous sulfate crystals Formula: FeSO47H2O (also known as green vitriol) Molecular Weight: 278.05 ferrous sulfate effects Product name: ferrous sulfate product standards: GB10531-89 Chemical Formula: FeSO47H2O; ferrous sulfate formula FeSO4.7H2O, sulfuric acid a rare metal products production output during the byproduct appearance of pale green or yellowish green odorless crystalline solid, there is convergence with a salty taste. Join agreed to adjust the amount of alkaline water PH value, combine with water and suspended solids, and accelerate the precipitation, mainly used in water purification and industrial wastewater treatment, but also has a bactericidal effect. The relative density of 1.899 (14.8 ℃), melting point 64 ℃, losing six molecules of water of crystallization at 90 ℃, lose the whole crystal water at 300 ℃. In dry air easily weathered, gradual oxidation in moist air to form brown alkaline sulfate. Anhydrous is a white powder, relative density 3.4, and the role of water becomes blue and green. pH (1 +10 solution) 3.7. 1g product can be dissolved in water or 0.5mL about 1.5mL25 ℃ boiling water, insoluble in ethanol. This product theoretical iron content of 20.45%. Characters: blue green monoclinic crystal, the product appearance is light green or yellowish green crystalline solid. Soluble in water, glycerol, not in alcohol, corrosive, deliquescence weathering. Ferrous sulfate Usage: sewage treatment, fertilizer, pesticides, catalysts, disinfectants, magnetic, and other physical and chemical industry, ferrous sulfate index: Item Index drinking water treatment treatment with Premium grade First grade Qualified superior product with industrial water First grade Qualified ferrous sulfate (FeSO 4 · 7H 2 O) content% ≥ 97.0 94.0 90.0 97.0 94.0 90.0 titanium dioxide (TiO 2) content,% ≤ 0.5 0.5 0.75 0.5 0.5 0.75 Water insoluble% ≤ 0.2 0.5 0.75 0.2 0.5 0.75 Free acid (H 2 SO 4) content,% ≤ 0.35 1.0 2.0 --- arsenic (As) content% ≤ 0.0005 0.0005 0.0005 --- Heavy metals (Pb) content,% ≤ 0.002 0.002 0.002; sulfuric acid Ferrous sulfate is a rare metal production process of the output product of the product, may be added to adjust the PH value of the agreed amount of alkaline water, combined with the organic suspended matter in water and to accelerate the precipitate, mainly used in water purification and industrial wastewater treatment , also has bactericidal effect. Ferrous sulfate role Uses: 1, ferrous sulfate is mainly used as flocculants: flocculation good, with a good bleaching ability, but also with the removal of heavy metal ions, to oil, phosphorus, sterilization and other functions, especially for dyeing wastewater bleaching and removal of COD, ferrite plating wastewater obvious effect of precipitation and its cheap, printing and dyeing, electroplating wastewater treatment worthy choice. 2, ferrous sulfate can be used as food additives, pigments, the raw materials used in the electronics industry, hydrogen sulfide deodorant, soil improvers, such as industrial catalysts.
