Two well-defined one-electron waves are observed on the polarograms for the reduction of 3-cyanoquinoline in 9S"/" ethanol containing 1M ammonium acetate. During macroscale electrolysis at a potential on the plateau of either wave, the ratio of the wave-heights remains unity. Polarographic and volta
The depolarization of p-nitrophenol at a rotating micro-cathode at different current densities and temperatures has been studied. The influence of acid strength and pH on the reduction has been investigated. Results obtained with a copper cathode and an amalgamated copper cathode are reported. The p
