Product Description

Product Description

Ferrous Sulfate

CAS:7720-78-7


Product Introduction:
Ferrous sulfate heptahydrate commonly known as alum, is a blue-green crystal or particles, mainly used for iron fertilizer, pesticides, pigments, medicine, etc., in addition to chromatographic analysis reagents. It is a by-product of the sulfuric acid process in the production of a rare metal product. The product is a light green or yellowish-green crystalline solid.

Product Features:
The color of ferrous sulfate heptahydrate is green, monoclinic crystal or particle, no odor, relative density 1.898, melting point 64ºC. Easily soluble in water, (48.6g/100ml water at 50ºC) red heat decomposition to form ferric trioxide, soluble in glycerol, insoluble in ethanol, corrosive, in dry air will be weathered. At 56.6ºC, the heptahydrate is transformed into tetrachlates, and at 64.6ºC, it becomes monohydrate. At 90ºC, six crystalline water is lost, and at 300ºC, all crystalline water is lost to form anhydrous substance. At red heat, SO2 and SO3 are decomposed and released. It's corrosive. It fluoresces in dry air. The anhydrous substance is a white powder, but when it is mixed with water it turns blue-green.


Usage:
1.As a reducing agent: ferrous sulfate is a strong reducing agent, can be the water content of the electroplating plant chromium wastewater hexavalent chromium reduction into trivalent chromium.
2.As a flocculant: ferrous sulfate is widely used as a flocculant, it has the following advantages as a flocculant: Sedimentation speed, large granular sludge, the sludge volume small and compact, except for the color effect is good, very suitable for as a textile wastewater, printing and dyeing, washing processing), non-toxic and beneficial organisms (very suitable for use in the subsequent biochemical treatment process of wastewater treatment system), without changing the original technology, and the price is low, as a flocculant, Ferrous sulfate can replace polymeric aluminum, basic aluminum chloride, polymeric iron, aluminum sulfate and so on. Dyeing, electroplating and other wastewater treatment worthy of the product.
3.As a precipitator: ferrous sulfate and sulfide, phosphate and other precipitation, so as to remove sulfide, phosphate, etc., for example, with ferrous sulfate treatment of printing and dyeing plant sulfur wastewater.
