ferric sulfate is a yellowish white powder or a monoclinic crystal. Relative density (dl8)3.097. Easy to absorb moisture, soluble in water, aqueous solution was acidic reaction. Slightly soluble in ethanol, insoluble in acetone, ethyl acetate. The hydrolysis is slow in aqueous solution. The iron sulfate crystallizes from the aqueous solution into hydrate crystals with 12, 10, 9, 7, 6 or 3 water molecules. Nine hydrate is yellow, the relative density of 2.1,480 degrees Celsius decomposition, very soluble in water, 20 degrees Celsius 1009 water can dissolve 4409. Hydrate is easily weathered in Air
ferric sulfate is obtained by dissolving ferric oxide in boiling sulfuric acid having a content of 75% to 80%. Or oxidation of pyrite with nitric acid.
iron sulfate is used in the field of water treatment as a coagulant for water purification and a sludge treatment agent, and is mainly used in the purification treatment of drinking water and the purification treatment of industrial water, various industrial wastewaters, urban sewage, and the like. It has excellent turbidity removal, decolorization, oil removal, deodorization, sterilization, algae removal, phosphorus removal, grease removal, removal of COD, BOD and heavy metal ions. The use of ferric sulfate and ferric chloride mixture and calcium hydroxide to treat sludge discharged from sewage treatment plants can reduce the amount of sludge. Ferric sulfate can also be used as a raw material for the manufacture of alum and other iron salts and pigments, as an etchant for aluminum devices and as a scavenger for certain industrial gases, and as a biocide, it can also be used for the pickling of metals, especially stainless steel and copper. The acidic solution serves as an oxidizing medium for the extraction of useful components from the ore.
is a low toxicity product, and its acidic solution has a stimulating effect on the skin. When in contact with the skin, can be washed with water, non-combustible and non-explosive. In the storage and transportation, strict protection against toxic substances pollution, rain and moisture.
