摘　　要：以离子液体N-丁基-N-甲基哌啶六氟磷酸盐为修饰剂与石墨粉和石蜡相混合制备了一种新型离子液体修饰碳糊电极(ILCPE)。采用扫描电镜对其表面形貌进行表征,以铁氰化钾作为电化学探针研究了IL-CPE的电化学性能,并与传统碳糊电极进行对比。实验数据表明该离子液体所制备的IL-CPE具有高导电性,电流响应显著增加且电极反应可逆性变好。Ionic liquids N-butyl-N-methyl-piperidinium hexafluorophosphate was used as the modifier and the binder,which was mixed with carbon powder to prepare a new kind of ionic liquid modified carbon paste electrode（ IL-CPE）. The surface morphorography of IL-CPE was characterized by scanning electron microscopy. By using ferricyanide solution as the electrochemical probe,electrochemical behaviors of IL-CPE were investigated and the results were compared with CPE. The results indicated that the presence of IL in CPE resulted in the high conductivity with the electrochemical response increased greatly. Also the high viscosity of IL resulted in excellent mechanical strength of the modified electrode.
