Sodium Thiosulfate Uses

Sodium thiosulfate is a versatile compound used in various industries. It acts as a new type of germicide with stomach poisoning, systemic, and contact effects. It effectively controls pests like rice stem borers, rice splint combers, rice thrips, and pests on vegetables and fruit trees.

In the aquaculture industry, sodium thiosulfate is widely used due to its low cost, high efficiency, and environmentally friendly properties. It removes residual chlorine from water and degrades nitrites, improving water quality.

In fabric processing, sodium thiosulfate serves as a dechlorination agent after bleaching pulp and cotton fabrics. In the food industry, it functions as a chelating agent and antioxidant. Additionally, it plays a role in the pharmaceutical industry as a component in soaps and detergents.

For water treatment, sodium thiosulfate is used to dechlorinate drinking water and wastewater. It also works as a bactericide and a copper corrosion inhibitor for cooling water systems. Moreover, it acts as a deoxidizer in boiler water systems and helps treat cyanide-containing wastewater.
