✦ Synopsis

Differential pulse polarographic studies of nitrobenzene in aqueous ethanol reveal complex behaviour involving solvent composition, viscosity and PH. Both reduction potential and peak reduction current are dependent on all three parameters. Limits of detection of ca. 2 X lo-' M and a linear working range up to 10m3 M nitrobenzene in ethanol-water (80:20) at pH 6 were recorded. No adsorptive accumulation of nitrobenzene onto the hanging mercury drop electrode employed was observed under any condition in the aqueous ethanol mixtures.
