Product overview

Sodium sulfide is also known as alkali sulfide, smelly soda, smelly alkali, at room temperature pure product is colorless or slightly purple, often pink, brown red, yellow block, industrial sodium sulfide due to impurities, soluble in water, insoluble in ether, slightly soluble in ethanol, insoluble in ether, its aqueous solution is strongly alkaline, touching the skin and hair will cause burns, easy oxidation in the air, toxic.

The reason why the red film is red is mainly the iron ion content.

Applications

①In the water treatment industry, it is mainly used to treat electroplating or other wastewater containing metal ions. The precipitation of metal ions by sulfur ions is used to remove metal ions, such as germanium, tin, lead, bismuth, silver, cadmium, copper, mercury, zinc, manganese, etc.

②In dyeing industry, for the production of sulphide dye, is the raw material of sulphide blue. Sodium sulfide also used as an aid to dissolving sulphide dyes.

③In leather industry, it is used for hydrolysis to dehair rawhide, also.
