分别以硝基苯(NB)、苯乙酮(ACP)、4-甲基-2-戊酮(MIBK)三种不同的有机溶剂作为悬液电极, 利用三电极体系伏安法比较其在液/液界面上对碘的不同的电化学特性. 在上述研究的基础上, 选用MIBK作为有机溶剂对碘进行萃取分析, 利用伏安法测定了水溶液中Cu(II)的含量, 同时研究了温度和萃取时间对该体系的影响.

Three different organic solvents, nitrobenzene (NB), acetophenone (ACP) and methyl isobutyl ketone (MIBK) have been used as an electrolyte hanging electrode respectively. The voltammetric behavior of the iodine at the liquid/liquid interfaces was compared with a classic three-electrode system. The content of the Cu(II) in solution was determined with voltammetry of extracting iodine with MIBK. And the effects of temperature and extracting time were also studied.

Key words: electrolyte hanging electrode, liquid/liquid interface, three electrode system, methyl isobutyl ketone (MIBK), cyclic voltammetry
