Description

Iron Potassium Bis(Sulphate), also known as iron potassium sulfate, is a versatile inorganic salt with significant industrial utility. Its primary value lies in its dual functionality as a source of both iron and potassium ions in various chemical processes and formulations. This compound is particularly relevant for manufacturers in the chemical synthesis, water treatment, and agricultural sectors seeking reliable reagent-grade materials. Consistent quality and supply chain stability are critical for these applications, which our product is designed to provide.

Application

• Chemical Synthesis: Acts as a catalyst or a reagent in specific organic and inorganic synthesis reactions.
• Water Treatment: Used in coagulation and flocculation processes for the purification of industrial wastewater.
• Laboratory Reagent: Serves as a high-purity analytical standard and reagent in research and quality control laboratories.
• Agriculture (Soil Amendment): Provides a combined source of soluble iron and potassium for correcting specific nutrient deficiencies in soils, though application rates must be carefully managed.
• Feed Additive Precursor: Can be processed as a mineral nutrient source in animal feed formulations, subject to appropriate purity grades and regulatory approvals.
• Surface Treatment: Employed in certain metal finishing and surface conditioning baths.

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). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
