| Abstract | A spectrophotometric method is described for the determination of saccharin. The Intended reacts with diazotised 4-nitroaniline in alkaline solution to form a stable brown coloured azo dye. The absorbance is measured at 427 nm. Beer’s law is obeyed over the concentration range of 10 − 200 μg of saccharin in a final volume of 25 ml, i.e. , ( 0.4 − 8 ppm ) with a molar absorptivity of 2.75×10 1. mol − 1 , cm − 1 and Sandell sensitivity index is 0.0088 μg. cm , a relative error of − 0.541 to + 1.851 % and a relative standard deviation of a ± 0.35 to ± 2.2 %, depending on the concentration level. Further, the method requires neither temperature control nor solvent extraction.
