Abstract
Differential pulse polarographic studies of nitrobenzene in aqueous et hanol reveal complex behaviour involving solvent composition, viscosit y and pH. Both reduction potential and peak reduction current are depe ndent on all three parameters. Limits of detection of ca. 2 X 10(-7) M and a linear working range up to 10(-3) M nitrobenzene in ethanol-wat er (80:20) at pH 6 were recorded. No adsorptive accumulation of nitrob enzene onto the hanging mercury drop electrode employed was observed u nder any condition in the aqueous ethanol mixtures.
