Description

Aluminum Zinc Sulfate is a versatile inorganic salt compound with a unique combination of aluminum and zinc cations. This dual-cation composition provides synergistic properties valuable for industrial processes requiring controlled precipitation, coagulation, or nutrient delivery. It is primarily utilized in water treatment, agriculture, and as a specialty chemical precursor. The compound is commercially significant for its role in creating advanced materials and formulations.

Application

• Water & Wastewater Treatment: Acts as a high-performance coagulant and flocculant for the removal of suspended solids, phosphates, and organic matter in industrial and municipal water systems.
• Agricultural Micronutrient Fertilizer: Serves as a source of both zinc and aluminum for soil amendment and foliar sprays, correcting nutrient deficiencies in crops.
• Paper Manufacturing: Used in sizing and retention aid formulations to improve paper strength, water resistance, and filler retention.
• Textile Industry: Employed as a mordant in dyeing processes to improve the fastness and uniformity of color on fabrics.
• Chemical Synthesis: Functions as a catalyst or precursor in the production of other aluminum and zinc-based chemicals, pigments, and fire retardants.
• Leather Tanning: Utilized as a mineral tanning agent to stabilize collagen fibers and produce durable leather.

Quality Control

Our Aluminum Zinc Sulfate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Product specifications are verified through rigorous analytical testing, including assay, heavy metal limits, and loss on drying. A Certificate of Analysis (COA) detailing purity and conformance to agreed specifications is provided with every shipment to guarantee quality assurance for your processes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases.
