Sodium sulfide: Uses and Safety

Uses of Sodium sulfide

Sodium sulphide is commonly used in the pulp and paper industry for the manufacture of paper products. It is used as a bleaching agent and to remove lignin from wood pulp. In the textile industry it is used as a dyeing agent for cotton and wool fibres. In the leather industry, sodium sulphide 98% anhydrous is used to remove hair and feathers from animal skins and as a tanning agent. In addition, it is used in the production of sulphur dyes, insecticides and pharmaceuticals. Its reducing properties also allow it to be used in the synthesis of organic compounds such as sulphur esters and thione.98% Anhydrous Sodium Sulphide is also widely used in the mineral flotation process, which helps to separate valuable minerals from the ore.
