Sodium Sulfide

Sodium sulfide is a chemical compound with a chemical formula Na2S. this material  is used in the pulp and paper industry, water treatment, textile industry, and various chemical manufacturing processes including the production of rubber chemicals, sulfur dyes and oil recovery.

Along with its hydrate form, it releases hydrogen sulfide (H2S) when in contact with moist air. H2S is an endogenous gaseous transmitter that exhibits anti-inflammatory and antiapoptotic properties.

Along with other sulfides, the anti-inflammatory and tissue-protective effects of sodium sulfide have been investigated in models of inflammation and oxidative stress. Interestingly, sodium sulfide was shown to have some cardioprotective role against cardiac ischemia or reperfusion injury, as well as protect lungs against ventilator-induced lung injury.

However the clinical significance and mechanism of action of this product  and replication of results across other studies are not yet fully determined.

Applications of Sodium Sulfide

this product  is used in many industries; for example, the pulp and paper industry and in leather processing to remove hair from hides. it may be used in the making of colors and dyes. Sodium sulfide can also be used in the manufacture of other chemicals, metals or in mining processes and in waste water, soil and process sludge treatment.

In organic chemicals, dyes rayon, leather and paper, in hydrometallurgy of gold ore, sulfiding oxidized lead and copper ores, and as an analytical reagentSodium sulfide is used mainly in the pulp and paper industry in the Kraft process. It serves as an oxygen scavenger agent in water treatment.

Other applications include ore flotation, oil recovery, making dyes and detergents. In the leather processing industry, it is utilized for liming operation as an unhairing agent. It is also used in the textile industry as a bleaching and desulfurizing agent and as a dechlorinating agent in chemical photography for toning black and white photographs as well as metals precipitant.

It plays an important role as a sulfonation and sulfomethylation agent in the chemical industry and in the production of rubber chemicals, sulfur dyes and other chemical compounds.
