SODIUM SULFIDE, Sulphide exporter and supplier. Sodium Sulfide 60% Flakes
Sodium sulfide is the chemical compound with the formula Na2S and it has an antfluorite structure. It’s a yellow appearance, water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S emit hydrogen sulfide, which smells like rotten eggs.
Sodium sulfide chemical formula Na2S.
Sodium sulfide 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.
The solution of Sodium Sulphide obtained from the process is concentrated to 10-12% and is available at different percentages in tanker loads. In Industries Na2S is produced by carbothermic reduction of sodium sulfate often using coal. It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds. It is used in other applications including ore flotation, oil recovery, making dyes, and detergent.
Do you know Sodium Sulfide solution is used during water treatment, as a metal precipitator.
Sodium sulfide (Na₂S) used in water treatment as a metal precipitator. It works by reacting with heavy metals in wastewater to form insoluble metal sulfides, which can then be removed by sedimentation or filtration. This process is particularly useful for removing toxic metals like lead, mercury, and cadmium, which are often present in industrial wastewater.
When sodium sulfide is added to the water, it dissociates into sodium ions (Na⁺) and sulfide ions (S²⁻). The sulfide ions bond with metal ions to create solid compounds, which can then be physically separated from the water. This treatment not only helps meet environmental standards but also reduces the risk of heavy metal pollution, which is highly harmful to ecosystems and human health.
- Used as Depilatory reagent and in pharmaceutical Industries.
- Used in obtaining the sulphur Black Dyes.
- Used in Ore Floatation.
- Used in Engraving and also used as analytical reagent.
- Used for removing sulphur in viscous Rayon Industry.
- Used in Industries to remove heavy metals from waste water.
- Used in the manufacture of lubricating oils.
- Used in the production of polysulphide elastomers.
- Used in Synthetic cooking liquor.
