Application of Sodium Sulphide

  1. Water Treatment: Sodium Sulphide is used to remove heavy metals from wastewater by precipitating them as insoluble metal sulfides, which can then be filtered out. This process is crucial for meeting environmental regulations and ensuring safe water discharge.
  2. Leather Processing: In the leather industry, Sodium Sulphide is employed to remove hair from hides during the unhairing process. It acts as a reducing agent, breaking down keratin and facilitating the removal of hair, thus preparing the hides for further processing.
  3. Textile Industry: Sodium Sulphide is used in the textile industry for dyeing and bleaching processes. It helps in the reduction of dyes, making them soluble and allowing for uniform application on fabrics.
  4. Paper Manufacturing: As a bleaching agent, Sodium Sulphide is used in the paper industry to remove lignin from wood pulp, resulting in brighter and higher-quality paper products.
  5. Chemical Synthesis: Sodium Sulphide serves as a key intermediate in the synthesis of various chemicals, including sulfur dyes and other sulfur-containing compounds, due to its strong reducing properties.
