Description	The apparent pK(a) values of 6-benzylaminopurine (BAP) and its 4-chloro-6-benzylaminopurine and 4-methoxy-6-benzylaminopurine derivatives were determined in good agreement with voltammetric approaches and with spectrophotometry. Whereas at acidic pH values two overlapped reduction peaks on the mercury electrode were obtained, at more slightly alkaline solutions one reduction signal was measured not only for BAP but also for its derivatives. Furthermore, high scan rates, low ionic strength concentration and a high percentage of the organic solvent cause the best splitting of signals. For the detailed study of such a phenomenon, elimination voltammetry with linear scan (EVLS) was used concluding that the reasons of the peak splitting seem to be related to two different reduction mechanisms that take place on the electrode mainly controlled by adsorption.
