摘要/Abstract

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Ba²⁺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Ba²⁺以及用其它方法难以测定的DB18-C-6.

关键词: 液/液微界面, 辅助离子转移, 不对称扫描速率循环伏安法

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
