Factory Supply Ferric Subsulfate, with the CAS number 1310 - 45 - 8, is a chemical compound that has attracted significant attention in various industries due to its unique properties and low price. Ferric subsulfate is a salt with the general formula Fe2(SO4)3·xH2O. It usually appears as a yellowish - brown crystalline solid. The purity of our factory - supplied product can reach a high level, typically above 95%, meeting the strict requirements of different applications.
It has a relative molecular mass that varies depending on the degree of hydration. The density of ferric subsulfate is approximately 3.097 g/cm³. It is soluble in water, and the aqueous solution is acidic, which is an important characteristic for its subsequent applications.
1. Water Treatment: Ferric subsulfate is widely used in water treatment processes. It can act as a coagulant to remove suspended solids, turbidity, and some heavy metals from water. By forming flocs with impurities in the water, it makes the water clearer and cleaner, meeting the standards for drinking water or industrial water use.
2. Pigment Industry: It can be used as a raw material for the production of iron oxide pigments. These pigments are widely used in paints, coatings, and plastics to provide color and improve the durability and weather resistance of products.
3. Chemical Industry: In the chemical industry, ferric subsulfate can be used as an oxidizing agent in some chemical reactions. It can participate in redox reactions to promote the transformation of substances and is used in the synthesis of some organic compounds.
1. Water Treatment: When using ferric subsulfate for water treatment, first, determine the appropriate dosage based on the quality of the water to be treated. Usually, it is added to the water in a dissolved state. The solution should be well - mixed with the water to ensure effective coagulation. After the flocs are formed, they can be removed by sedimentation or filtration.
2. Pigment Industry: In the pigment industry, ferric subsulfate needs to be further processed through a series of chemical reactions to form iron oxide pigments. The reaction conditions, such as temperature, pH value, and reaction time, need to be strictly controlled to obtain high - quality pigments.
3. Chemical Industry: When used as an oxidizing agent, ferric subsulfate is added to the reaction system according to the stoichiometric ratio of the reaction. Appropriate reaction conditions, such as temperature and solvent, should be selected to ensure the smooth progress of the reaction.
1. Water Treatment Case: A municipal water treatment plant in a certain area was facing the problem of high turbidity in raw water. They used our factory - supplied ferric subsulfate as a coagulant. After adding an appropriate amount of ferric subsulfate solution to the water and stirring well, obvious flocs were formed within a short time. Through subsequent sedimentation and filtration processes, the turbidity of the treated water was significantly reduced from the original 50 NTU to less than 1 NTU, meeting the drinking water standards.
2. Pigment Industry Case: A paint manufacturing company used ferric subsulfate as a raw material to produce iron oxide yellow pigment. By strictly controlling the reaction conditions, such as reacting at a temperature of 80°C and a pH value of 4 - 5, they obtained high - quality iron oxide yellow pigment with bright color and good dispersion. The pigment was used in exterior wall paints, and the painted walls showed excellent weather resistance and color retention, which was well - received by customers.
3. Chemical Industry Case: In a chemical synthesis laboratory, ferric subsulfate was used as an oxidizing agent in the synthesis of a certain organic compound. By adding ferric subsulfate in an appropriate amount to the reaction system and reacting at a specific temperature and in a suitable solvent, the yield of the target product reached more than 80%, which was much higher than the results obtained using other oxidizing agents.
