| Popis | Electrochemical and spectral behaviors of 6 – benzylaminopurine (6 – BAP) and its chlorine and methoxy derivatives have been studied by voltammetry, potentiometry and spectrophotometry. Using linear sweep voltammetry (LSV) in connection with a mercury electrode the reduction peaks of BAPs were observed. On the other hand, using elimination voltammetry with linear scan (EVLS) the differences in the reduction processes of derivatives studied were found. The EVLS confirmed the electron transfer in an adsorbed state. The pH value of water-methanol solutions was chosen according to the protonation constants of BAPs determined by both potentiometric and UV-Vis spectrophotometric titrations. The effect of methanol content and temperature on pKa values of 6-BAP was monitored. |
