Description

Sodium Hydrosulfide Hydrate is a versatile inorganic chemical compound primarily supplied as a hydrated solid. This material serves as a crucial source of the hydrosulfide anion (HS⁻), making it an essential reagent for sulfuration and precipitation reactions across multiple industries. Key industrial users include manufacturers in pulp & paper processing, leather tanning, mineral flotation, and as a precursor in specialty chemical synthesis.

Application

• Pulp & Paper Industry: Used in the kraft process for the production of wood pulp, acting as a sulfide source.
• Leather Processing: Employed as a depilatory agent in the tanning industry to remove hair from hides.
• Mining & Metallurgy: Utilized as a flotation agent in the separation and recovery of metal ores, particularly copper and molybdenum.
• Chemical Manufacturing: Serves as a key intermediate and sulfur source in the synthesis of various organic sulfur compounds, dyes, and pesticides.
• Wastewater Treatment: Applied for the precipitation and removal of heavy metal ions from industrial effluent.
• Textile Industry: Used in specific dyeing and printing processes.

Quality Control

Our Sodium Hydrosulfide Hydrate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay and impurity profile determination. A Certificate of Analysis (COA) detailing specific results for purity, heavy metals, and other relevant parameters is provided with each shipment to guarantee compliance with your technical requirements.

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 degradation.
