The polarographic behaviour of pyridine-2-carbaldehyde 2-pyridylhydrazone (PAPH) at a dropping-mercury electrode was studied in aqueous Britton-Robinson buffers containing 50percent 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 polarographic waves of PAPH have been investigated.The kinetic parameters for the electrode reaction at different pH values have been computed.
