Ferrous sulfate has a wide range of industrial applications, including the production of salt, ink, iron oxide red, and indigo. It is also used as a mordant in dyeing, a tanning agent in leather processing, a detergent, and a wood preservative. The company specializes in manufacturing ferrous sulfate monohydrate and ferrous sulfate heptahydrate, which are widely used in various industries. In the pharmaceutical sector, the product line includes cationic and anionic polyacrylamide, polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, ferric chloride, phosphoric acid, trisodium phosphate, potassium dihydrogen phosphate, and similar compounds.
Ferrous sulfate heptahydrate, with the molecular formula FeSO₄·7H₂O, is a by-product of the sulfuric acid process used to produce rare metal products. This compound appears as a pale green or yellowish-green crystalline solid. When added in appropriate amounts, it helps adjust the pH of alkaline water, binds with suspended solids, and accelerates sedimentation. It is commonly used in water purification and industrial wastewater treatment due to its ability to remove impurities and even exhibit bactericidal properties.
During the Cenozoic era, tectonic movements such as the Middle-earth Alpine and the Tertiary Himalayan events shaped the modern landscape, including the distribution of land and sea and the formation of mountain ranges. Climate zones became more distinct, and angiosperms flourished, especially grasses and legumes, leading to the development of grasslands without forests. These changes contributed to the creation of fertile soils and provided abundant feed resources for animals, ultimately creating favorable conditions for the evolution of mammals and the eventual emergence of humans.
This period marked a new stage in the dialectical development between organisms and their environment. Environmental changes created opportunities for biological growth, while the development of life itself influenced the transformation of matter and energy. Nutrients from geological cycles were incorporated into organic matter through biological processes, slowing down material loss and promoting recycling. This cycle helped maintain soil fertility and supported the continuous development of the biosphere, eventually leading to the rise of human civilization.
Agricultural-grade ferrous sulfate is commonly used to adjust soil pH, making it suitable for plants that thrive in slightly acidic conditions. It also provides essential iron to plants, helping prevent chlorosis caused by iron deficiency. In addition to soil improvement, it can be used to remove moss and lichens and acts as a pesticide to control diseases in wheat and fruit trees. Ferrous sulfate is also applied as a fertilizer, acting as a catalyst for chlorophyll synthesis and playing a vital role in plant nutrition. Gardeners often use it to eliminate moss from lawns and garden areas.
