摘　　要：室温离子液体的许多独特的性质为其在化学分离、电化学传感器、电池等领域展示了广阔的应用前景。室温离子液体作为有机反应介质,可以克服水溶液电化学窗口较窄的缺点,还可避免或减少造成二次污染的大量有机溶剂。利用离子液体的导电性。The electrochemical reduction dehalogenation of 2,4,6-tribromophenol in 1-butyl-3-methylimidazolium hexafluorophosphate room temperature ionic liquid was investigated.Cyclic voltammetry measurement results show that the reductive potential of dehalogenation at silver electrode is more positive than that at the glassy carbon electrode.More halogen atoms can be dehalogenated at silver electrode than at GC electrode with the same experimental conditions.This result indicates that silver electrode has excellent electrocatalytical activity on electrochemical reduction of organohalogencompounds.
