A spectrophotometric method for the simultaneous determination of sulpbathiaxole and sulphametaxine based on fourth-derivative solid-phase spectrophotometry is proposed. Both sulphonamides were fixed on a dextran-type cation-exchange gel at pH 2.5. The absorbance on the gel, packed in a l-mm silica
