摘要
应用液/液界面微电极对二苯并18-冠-6(DB18-C-6)辅助推动Ba^(2+)在1,2-二氯乙烷/水(DCE/W)界面转移的电化学过程进行了详细探讨,证明该过程遵循TIC机理,是受扩散控制的可逆过程。通过转移电流和反应物浓度之间的线性关系,测定了Ba^(2+)以及用其它方法难以测定的DB18-C-6。
The electrochemical behavior of Ba ̄(2+)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 TIC mechanism.Trace Ba ̄(2+)was analyzed together with DB18-C-6 which was difficult to determine by other methods.
