Description

Iron(III) Sulfate is an inorganic salt widely recognized for its role as a versatile coagulant and precipitating agent. Its primary commercial value lies in its effectiveness in water and wastewater treatment for removing suspended solids and phosphates. This product is essential for industries including municipal water treatment, metal surface finishing, and pigment manufacturing. We supply high-purity grades to meet the stringent demands of industrial and specialty chemical applications.

Application

• Water and Wastewater Treatment: Acts as a primary coagulant for turbidity removal and phosphate precipitation in municipal and industrial effluent.
• Metal Surface Treatment: Used in pickling baths for steel and as an etchant in the electronics industry for printed circuit boards.
• Pigment Production: Serves as a raw material in the manufacture of iron oxide pigments and inks.
• Soil Amendment: Applied in agriculture to correct iron deficiencies in crops and adjust soil pH.
• Chemical Synthesis: Functions as a catalyst or oxidizing agent in various organic synthesis processes.
• Odor Control: Utilized in waste treatment facilities to control hydrogen sulfide odors.

Quality Control

Our Iron(III) Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. We provide Certificates of Analysis (COA) with key parameters including assay, heavy metal content, and insoluble matter. Our production adheres to relevant industrial standards, and we can support compliance documentation for global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong bases and reducing agents.
