The oscillations of electrochemical potential difference between aqueous phases of a liquid membrane oscillator containing cationic surfactant are presented. By UV-VIS spectroscopy, the concentrations of liquid membrane components (nitrobenzene and picric acid) in the both aqueous phases were established during the oscillation process. It was shown that nitrobenzene molecules are transferred to the aqueous phases from the beginning of that dynamic process. Picric acid molecules are not observed in the donor phase, meanwhile, from the beginning of the process they are transported to the acceptor phase. It can be concluded that the transport of the liquid membrane components to the aqueous phases is not responsible for the observed oscillations of electrochemical potential difference.
