多壁碳纳米管-离子液体修饰电极测定Cu~（2＋）
Detection of Cu（Ⅱ） by Multi-walled Carbon Nanotube-Ionic Liquid Modified Electrode
摘要
Abstract
The modified electrode was prepared by coating the mixture of multi-walled carbon nanotube particles（MWC-NT） and the ionic liquid（[BMIM]PF6） on the glassy carbon electrode surface.The accumulative and electrochemical behavior of Cu（Ⅱ） on the modified electrode was investigated.The sensitive anodic stripping peak of Cu（Ⅱ） was obtained and was compared with that obtained using glassy carbon electrode.Under the optimum conditions,stripping peak current of Cu（Ⅱ）has good linearity with concentration in the range of 1.0 × 10-6 ～ 1.0 × 10-5mol/L,and the detection limit is 9.0 × 10-8 mol/L.The modified sensor is easy to prepare with good repeatability and can be use for determination of trace Cu（II）.关键词
