Product Applications
Ferrous Sulfate Heptahydrate is used for the production of high-end lithium battery cathode materials, and iron phosphate raw materials; Used as analytical reagent to analyze and determine platinum, selenium, nitrate, nitrite, etc; It is also used for photographic plate making, ferrite raw materials, iron intensifiers and fruit and vegetable colorants; In agriculture, it can be used as a pesticide and fertilizer, which can prevent and control wheat smut, apple and pear scab, and fruit decay. It is also a trace element fertilizer, which can accelerate the rejuvenation of rice and sugar beet, adjust the pH value of soil, supplement iron to plants, and remove moss and lichens from tree trunks; Raw materials for manufacturing magnetic iron oxide, iron oxide red and iron blue inorganic pigments, iron catalysts and high-end polymeric ferric sulfate; Used as local astringent and blood tonic in medicine; Food grade: used as nutritional supplement, such as iron enhancer, fruit and vegetable chromogenic agent; Feed grade ferrous sulfate is used as an iron supplement in feed processing.
Ferrous sulfate: alias: ferrous sulfate, ferrous sulfate heptahydrate, green alum, drying ferrous sulfate. It can be used as reducing agent in electroplating plant, flocculant in industrial wastewater, precipitant in printing and dyeing plant, raw material in Tiehong plant, raw material in pesticide plant, raw material in chemical fertilizer plant, fertilization in ferrous sulfate flowers, etc. It is widely used for flocculation, clarification and decolorization of printing and dyeing, papermaking, domestic sewage and industrial wastewater. Ferrous sulfate can also be used to treat chromium containing wastewater and cadmium containing wastewater Equal high alkalinity and high chroma wastewater treatment can reduce a large amount of investment in neutralization acid.
