摘要
通过电聚合酸性铬蓝K(ACBK)于多壁碳纳米管(MWNTs)修饰玻碳(GC)电极上构建了一种新的修饰电极。研究了该电极的电化学性质,结果表明该电极表现出优异的电催化和选择性能,可在异构体存在下伏安法选择测定邻苯二酚。线性范围在1×10-6-1×10-4mol.L-1,最低检测限为1×10-7mol.L-1。构建的电极对水样进行了测定并获得了满意的结果。
A novel modified electrode was fabricated by eleetropolymerized of acid chrome blue K at the multi - wailed carbon nanotubes modified glassy carbon electrode. The constructed electrode showed excellent reproduelbillty and stability. The electrode developed was used to seleetlve determination of eateehol with the eoexlstlng of the isomers in environmental samples. There was a linear relationship at the range 1×10^-6 - 1×10^-4 mol L^-1 of eateehol with the anodle peak currents and the detection limits was estimated to be 1×10^- 7 mol L^-1. Actual water sample was analysed and satisfactory result was obtained.
