- Possible fields of application of sodium sulfide Na2S
Sodium sulfide can be used in many ways. The product is used, among other things, in tanning as depilatory agents, as well as in mining for ore flotation as well as in organic chemistry as a reducing agent. Furthermore, sodium sulfide is used in the treatment of waste water for heavy metal precipitation as well as for the production of sulfur dyes. Further application possibilities of the substance are the coloring of glass, the removal of nitric oxides from exhaust gasses as well as the wood decomposition. In the area of black-and-white photography in the darkroom as well as in lithography, sodium sulfide is used as a sepia toner for sulfur toning. The silver in photopaper is modified with the aid of sodium sulfide to silver sulfide.
Leather production is an important area of application. Experts are talking about the process of liming. As a result, the animal hair is removed from the skin, the animal skin loses its fat content and is prepared for the tannery. This determines the later structure and property of the leather. The softer the leather in the end result, the stronger must be cremated. Leather for soles e.g. Must be cremated only briefly. The term "liming" comes from the time when wood ash was used. Today, for example, sodium sulfide is used in the industrial production of leather. However, this results in environmentally harmful waste water, which must be clarified and processed.
Sodium sulfide is flake-shaped as a solid and available as a lye in liquid form. In combination with an acid, toxic, flammable hydrogen sulfide is released. Sodium sulfide reacts with oxidizing agents such as potassium permanganate or potassium dichromate. The solubility in water is good, the resulting solution being alkaline and corrosive. If sodium sulfide is stored for a long time, it turns yellowish together with water.
Further fields of application of sodium sulfide Na2S
Sodium sulfide from TIB Chemicals is a universally applicable product in industry. Especially in black and white photography, sodium sulfide is used to color the film with a sepia toning. In industry, sodium sulfide also acts as a reducing agent. Furthermore, sodium sulfide is used to treat chromium compounds in wastewater. The
product cleaves chemical complexes. The problem is that hydrogen sulfide escapes during use, enters the sewage system and can lead to unpleasant odors.It stands out due to its versatile use and is easy to store in the form of scales. Since sodium sulfide can develop toxic fumes in combination with acids, it is recommended that only qualified and experienced employees work with the material. In addition, remedial measures must be taken to neutralize the unpleasant odor.
Important functions are taken by sodium sulfide Na2S (CAS No. 1313-82-2) in the following areas:
• Leather production
• Production of sulfur paints
• Production of titanium dioxide
• Water treatment
• Heavy metal precipitation
• for the elimination of organic mercury compounds
• for ore flotation
• as a reducing agentConcluding remarks on the use of sodium sulfide Na2S
Sodium sulfide is widely used in industry, for example in the leather industry or in mining. It serves as a reducing agent and is used, among other things, in the textile industry. In addition, sodium sulfide is suitable for water treatment. Sodium sulfide can also be used in the production of sulfur paints.
