Indirect Spectrophotometric Determination of Thiosulphate

A. S. Dhomane and A. Venkatachalam

Indirect spectrophotometric method for trace determination of thiosulphate has been developed. The method is based on decrease in absorbance of ferric salicylate complex solution by thiosulphate. Up to 5 ppm of thiosulphate can be determined with a standard deviation of 0.046 ppm.
