Ferrous Sulfate Heptahydrate

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.

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.

Ferrous sulfate can be used as a reducing agent in electroplating plants, industrial wastewater as a flocculant, printing and dyeing plants as a precipitating agent, as raw materials for iron red plants, as raw materials for agrochemical plants, as raw materials for fertilizer plants, ferrous sulfate fertilizer in flowers and so on.

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.

Ferrous sulfate heptahydrate, commonly known as alum, is soluble in water, slightly soluble in alcohol, and soluble in anhydrous methanol.
In industry, it is used to produce iron salt, ink, iron oxide red and indigo, mordant, tanning agent, water purifying agent, wood preservative and disinfectant, etc.in agriculture, it is used as chemica

Ferrous sulfate can be used to make iron salts, iron oxide pigments, mordants, water purification agents, preservatives, disinfectants, etc

Ferrous sulfate use in medical

Iron(II) sulfate is sold as ferrous sulfate, a soil amendment for lowering the pH of a high alkaline soil so that plants can access the soil's nutrients. In horticulture it is used for treating iron chlorosis.
 
Ferrous sulfate can be used to stain concrete and some limestones and sandstones a yellowish rust color. Woodworkers use ferrous sulfate solutions to color maple wood a silvery hue.
