1. Sodium thiosulphate can adjust the PH balance of water quality in aquaculture; it can also absorb organic suspended solids in water bodies, thereby purifying water quality.

2. Sodium thiosulfate solution can dissolve the unsensitized silver bromide in the developed photographic film into a colorless complex and remove it, so it is a commonly used fixing agent.

3. Reducing agent for dichromate when tanning leather.

4. In the paper industry, it is used as a chlorine remover after pulp bleaching.

5. In the printing and dyeing industry, it is used as a dechlorination agent after bleaching cotton fabrics, a sulfur dye for knitted fabrics, and an anti-whitening agent for indigo dyes.
