Effect of Bisphenol a on the Facilitated Transfer of K+ By Dibenzo-18-Crown-6 across the Water|1,2-Dichloroethane Interface

In the present work, the effects of bisphenol A on the facilitated transfer of K+ by the dibenzo-18-crown-6 across the water|1,2-dichloroethane interface was studied. The electrochemical studies were carried out through Cyclic Voltammetry and Electrochemical Impedance Spectroscopy. The results indicate that bisphenol A does not transfer across the interface, instead this seems to inhibit the transfer of K+ across the interface. It was observed that the transfer currents of this cation decrease as the concentration of bisphenol A in the organic phase increases. The partial inhibition was due to the accumulation of bisphenol A at the interface on the side of the organic phase. The values of the kinetic constants of the cation transfer were determined by EIS and showed a change depending on the concentration of bisphenol A at the interface. This work can be used as a model system to understand the processes of ion transfer in biological systems.
