Abstract: The electrochemical behavior of Ba2+ion transfer assisted by DB18-C-6 has been studied in detail by using the dual-section liquid/liquid interface microelectrodes.The experimental results demonstrated that the process was reversible,diffusion-controlled and abided by TICmechanism.Trace Ba2+was analyzed together with DB18-C-6 which was difficult to determine by other methods.

Key words: Liquid/liquid microinterface, Assisted ion transfer, Asymmetric sweep ratevoltammetry
