Polarographic Determination Of Some Sulphonamide Derivatives In Pharmaceutical Preparations
A polarographic catalytic method is developed for the determination of sulpha drugs in presence of chromium (VI). The drugs produced a catalytic peak at - 1.7 V vs Saturated Calomel Electrode (SCE) in a buffer solution of pH 9.6. Optimum conditions are established for the analytical method. The method can be used for the determination of Cr (VI) as well as hydrolysed drug in micro quantities.
