Description

Potassium Hydrosulfide is an inorganic salt primarily used as a powerful sulfiding and reducing agent in industrial processes. Its high reactivity makes it a critical intermediate for synthesizing sulfur-containing compounds and for metal recovery operations. This product is essential for manufacturers in the mining, chemical synthesis, and leather processing industries who require a reliable source of active hydrosulfide ions.

Application

• Mining & Metallurgy: Key reagent in the flotation process for the separation and recovery of copper, molybdenum, and other non-ferrous metal ores.
• Chemical Synthesis: Acts as a precursor and sulfiding agent in the production of specialty chemicals, including other sulfur compounds and organic intermediates.
• Leather Processing: Used in the unhairing and liming stages of leather tanning as a depilatory agent.
• Pulp & Paper Industry: Employed in certain pulping processes and as a source of sulfide in chemical recovery cycles.
• Analytical Chemistry: Serves as a laboratory reagent for qualitative analysis and precipitation reactions.
• Wastewater Treatment: Utilized for the precipitation of heavy metals from industrial effluents.

Quality Control

Our Potassium Hydrosulfide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. We adhere to relevant industrial standards and provide comprehensive Certificates of Analysis (COA) for every shipment, detailing key parameters such as assay, impurity profiles, and physical characteristics. Our quality system is designed to meet the rigorous demands of global B2B customers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizers. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture and decomposition. Recommended storage temperature is between 15°C and 25°C.
