OTHER USED
♦ In the photographic industry to protect developer solutions from oxidation.
♦ It is used in the production of rubber chemicals and other chemical compounds.
♦ It is use in other applications include ore flotation, oil recovery, food preservative, making dyes, and detergent.
Sodium sulfide solid has important pharmaceutical applications.It can be used as a raw material for some pharmaceutical products, such as those used to treat skin diseases.
Topical medications and medications to treat liver disease.Sodium Sulfide(Anhydrous) can also be used as an auxiliary drug in the treatment of cancer by selectively blocking tumor
growth of tumor cells to exert a therapeutic effect.In addition, Sodium Sulphide is used as an auxiliary drug to promote other drugs absorption and release.
In addition, Sodium Sulphide factory is often used to delay the onset of fires.Some objects are particularly easy to burn, and Sodium Sulphide Flake 1849 can cause them to burn. Flammable compounds, thereby reducing the probability of fire.sodium disulfide 60% Min can also be used in the production of flame retardant materials to improve the flame retardant properties of the body.
Emergency treatment of leakage
Isolate the leakage contaminated area and set up warning signs around it. Emergency personnel should wear gas masks and chemical protective clothing. Do not directly contact the leaked material. Avoid dust, collect it with a clean shovel in a dry, clean and covered container, and transport it to a waste disposal site. You can also rinse it with a large amount of water and put the diluted washing liquid into the wastewater system. In case of large-scale leakage, collect and recycle it or dispose of it harmlessly.
Wastewater treatment method
The wastewater that causes sulfide pollution is mainly alkaline wastewater, which can be neutralized. In the neutralization stage, the pH decreases and some hydrogen sulfide will escape into the atmosphere. At the same time, the heat generated by the neutralization reaction will also increase the release rate of hydrogen sulfide. Hydrogen sulfide is released in large quantities in the air, which will pollute the air and disturb the people. The chlorination method can also eliminate sulfide pollution, which is also one of the effective methods, but it requires a large amount of chlorine and is expensive. In addition, iron or non-toxic iron salts (such as iron sulfate, iron chloride, etc.) are added to the sulfide-contaminated wastewater. After 2 hours of aeration, active iron hydroxide is produced, and the sulfide can be removed in the form of iron sulfide precipitation. The wastewater with severe sulfide pollution can also be neutralized by flue gas first, and then treated by the activated sludge method.
