Abstract: The polarographic behaviour of pyridine-2-carbaldehyde 2-pyridylhydrazone(PAPH) at a dropping-mercury electrode was studied in aqueous Britton–Robinson buffers containing 50% ethanol. The polarograms consist of one wave in the acidic and alkaline medium. Two electrons are consumed in the splitting of the N–N bond to give-2-aminopyridine and pyridine-2-carbaldehyde. The adsorption effects of cationic, anionic, and non-ionic surfactants on the polargraphic waves of PAPH have been investigated. The kinetic parameters for the electrode reaction at different pH values have been computed.
