Polyferric sulfate, also known as polyferric sulfate, is an important inorganic polymer compound, and its active ingredients mainly include ferric sulfate ions. In the structure of polyferric sulfate, ferric sulfate ions play a key role. They are combined together by covalent bonds to form a polymer chain, which has a variety of applications, such as water treatment, textile industry, leather processing, etc.
The chemical formula of ferric sulfate ion is Fe(SO4)n, where n can have different values, and common forms include Fe2(SO4)3 and FeSO4. These ions play a cross-linking role in polyferric sulfate, promoting the formation of a stable structure between polymer chains, thus giving polyferric sulfate specific properties and functions.
Among the effective ingredients of polyferric sulfate, the content of ferric sulfate accounts for an important proportion, usually between 20-21%. This compound has excellent coagulation performance. Its high-charge molecular weight and the positive ions and hydroxyl groups in its structure enable it to adsorb suspended matter in the water well, thus achieving excellent flocculation effect. At the same time, polyferric sulfate also has the characteristics of fast hydrolysis rate, high floc density, and wide applicable pH range. It can effectively remove impurities such as organic matter, sulfide, heavy metal ions, etc. in water, and realize functions such as decolorization, deodorization, demulsification and sludge dehydration.
In industrial applications, polyferric sulfate is widely used due to its efficient water purification performance. Whether it is chemical water treatment in thermal power plants or wastewater treatment in industries such as steel, papermaking, and coal chemical industry, polyferric sulfate plays an important role. It can effectively remove harmful substances such as manganese oxide and iron oxide in water, reduce water hardness, and improve water quality.
In the field of water treatment, polyferric sulfate is widely used as a coagulant and flocculant to remove suspended solids, colloidal substances and heavy metal ions in water. Ferric sulfate ions can react with pollutants in water to form precipitation or coagulants, thereby achieving the effect of water purification. In addition, polyferric sulfate can also be used in sewage treatment, industrial wastewater treatment and other aspects.
In the textile industry, polyferric sulfate can be used as a colorant fixative, which helps improve the color fixation of dyes and improves the fastness and uniformity of dyeing. Ferric sulfate ions can react chemically with dyes to form dyeing complexes, which firmly adhere the dyes to the fiber surface and enhance the dyeing effect.
In leather processing, polyferric sulfate can be used as a tanning agent to help the residual protein in the leather combine with the tanning agent, enhancing the softness, wear resistance and water resistance of the leather. The iron sulfate ions react with the collagen in the leather to form a cross-linked structure, making the leather stronger and more durable.
In general, the active ingredient of polyferric sulfate is mainly ferric sulfate ion, which has a variety of applications in different fields, including water treatment, textile industry, leather processing, etc. It plays an important function and role through its specific chemical properties and mechanism of action.
