Ferric sulfate (II)(Br.E. Ferric sulfate (II)) or ferrous sulfate is a compound with the chemical formula FeSO 4. It is used in medicine to treat iron deficiency and also in industrial applications. Since ancient times, copper has been known as the green sulfuric acid, and the blue-green heptahydrate is the most common form of this material. All iron sulfates dissolve in water to form the same water complex [Fe(H2O)6]2+, which has an octahedral molecular geometry and is paramagnetic.
1. Nutritional supplementation. Together with other iron compounds, ferrous sulfate is used to fortify food and treat iron deficiency anemia. Constipation is a common and uncomfortable side effect associated with oral supplements. Fecal softeners are usually prescribed to prevent shrinkage.
2. Effluent treatment system. It is used for purifying drinking water and treating wastewater by means of sedimentation of impurities and flocculation.
3. Papermaking industry. It helps to sizing paper at neutral and alkaline pH levels, thereby improving paper quality (reducing spots and holes, and enhancing the formation and strength of the board) and sizing efficiency.
4. Textile industry. Fixation of naphthophenol-based dyes for cotton fabrics.
5. Other uses. Leather tanning, lubricating composition, flame retardant; Petroleum decolorizing agent
Application
1. As a reducing agent: Ferrous sulfate is a strong reducing agent that can reduce the hexavalent chromium in the chromium wastewater from electroplating plants to trivalent chromium.
2. As a flocculant: Ferrous sulfate is widely used as a flocculant and has the following advantages as a flocculant: The sedimentation speed is fast, the sludge particles are large, and the sludge volume is small and compact. Besides having a good color effect, it is very suitable for use as textile wastewater, printing and dyeing, and washing processing. It is non-toxic and beneficial to organisms (very suitable for use in the subsequent biochemical treatment process of the wastewater treatment system), does not change the original technology, and is low in price. As a flocculant, Ferrous sulfate can replace polyaluminium, basic aluminium chloride, polymeric iron, aluminium sulfate, etc. It is a worthy product for the treatment of wastewater from dyeing, electroplating, etc.
3. As a precipitating agent: Ferrous sulfate precipitates with sulfides, phosphates, etc., thereby removing sulfides, phosphates, etc. For example, ferrous sulfate is used to treat sulfur wastewater from dyeing and printing factories.
