The dc polarographic behavior of metronidazole is studied in McIlvaine buffers. The reduction is irreversible and exhibits two waves; the first is suitable for analytical purposes. The limiting current shows a linear dependence with the drug concentration in the range 0.02-1 mM. A new polarographic

β¦ Synopsis
A polarographic method is described for the simultaneous determination of sodium bisulfite and iproniazid in gel formulations. The standard deviation for the bisulfite determination was *O.OO:% and the precision t s at the 95 z confidence level was +O.OO,%. The standard deviation for the iproniazid determination was +0.03z and the precision f s at the 95% confidence level was =kO.O7Z.
