If the product is a liquid and requires desulfurization, dilute the desulfurizing agent with water at a ratio of 10 to 20 times, then slowly add it to the liquid product while stirring.

Industrial-grade desulfurizing agent

Sulfur Removing Agent Physical Properties: White or slightly yellowish spherical fine powder, odorless and tasteless. Density 5.47g/cm³, relative density 4.42-4.45. Melting point 1800°C, insoluble in water and alcohol. Slightly soluble in ammonia. Soluble in dilute acid and sodium hydroxide. Reacts with 30% hydrogen peroxide to release carbon dioxide, forming peroxides.

Sulfur Removal Agent Product Uses: Main raw material for sulfur removal agents and catalysts in the man-made silk industry, widely applicable in rubber products, paints, and other chemical products. In oil drilling, this product reacts with H2S to form a stable, insoluble ZnS, and does not affect the mud properties when added, thus effectively eliminating H2S contamination and corrosion. It is used as an anti-corrosive agent and sulfur removal agent in H2S-containing oil and gas wells. Also, it can be used industrially as a lightening constringent and in the preparation of calamine lotion.

Food-grade desulfurizing agent

This is a colorless, odorless white crystalline powder that can safely and efficiently remove residual SO2 from food, effectively controlling the SO2 content to meet national hygiene standards, enhancing food quality, and preventing secondary pollution. It is used in the processing of edible mushrooms, bamboo shoots, vegetables, fruits, candied fruits, rice noodles, bread products, and more, as well as in the processing of medicinal herbs and wooden chopsticks. Additionally, it is suitable for the removal of residual substances from sulfites such as sodium metabisulfite, sodium sulfite, and sodium thiosulfate used as bleaching agents.

After the product has been treated with sulfites for color, rinse with clean water and then use this cleaner. Dilute this cleaner with 10-50 times its volume of clean water before use, soak the treated item in the diluted solution for 15-30 minutes, or dilute with water at a ratio of 100-200 times, soak for 1-2 hours, then remove and rinse with clean water. The dilution ratio of this agent should be determined based on the residual SO2 content in the treated item. A higher concentration of the cleaner enhances its ability to remove SO2. It can reduce the residual SO2 content in the treated item from 1000mg/Kg to below 20mg/Kg, even to 0.
