Abstract
Abstract A simplified quantitative procedure for the determination of mixed sulfonamides in pharmaceuticals is presented. The components are resolved by paper chromatography and located by their fluorescence under short wavelength ultraviolet light. They are then eluted and determined colorimetrically by a revised Bratton-Marshall technique. Total time of analysis is less than 4 hours. Recoveries averaged 98.8% with a range of 95.7 to 103.4%. Mean deviation from the average was 1.4%.
