Abstract
Third-order and fourth-order derivative spectra have been used for determining sulphathiazole, sulphanilamide and their binary mixtures. The method is suitable for 1-22 micrograms ml-1 of sulphathiazole and for 0.5-14 micrograms ml-1 of sulphanilamide and can be applied for determining the sulphonamides in pharmaceuticals.
