METHOD FOR SPECTROPHOTOMETRIC DETERMINATION OF SULFANILAMIDES IN PHARMACEUTICAL PREPARATIONS

摘要

Method for spectro-photometric determination of sulfanilamides in pharmaceutical preparations includes interaction of silfanilamides with diazotizing and chromogenous analytical reagents with cooling on ice bath. As chromogenous analytical reagent one uses azo-dye tropeoline O with concentration from 1.5·10to 1.0·10in alkaline medium at pH 10-11, and diazotizing reagent sodium nitrite with concentration from 5·10to5·10.
