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.Usage1.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. | Product Name: | Ferrous Sulfate Heptahydrate |
