A simple ultraviolet spectrophotometric method for the assay of microgram amounts (0.1–25 μg/ml) of 16 different p-aminobenzenesulfonamides (sulfonamides) in 0.1 N sodium (Figure presented.) hydroxide has been developed. The method is simple, accurate, and highly sensitive within the limits of the experimental conditions described and can be used in pharmacies for the assay of sulfonamides in tablets and in pharmaceutical industries for quality control or environmental monitoring as well. The present method is more rapid than any analytical assay reported for these compounds thus far. The values of λmax and ϵmax for these sulfonamides have also been presented.
