摘要
螺旋碳纳米管(HCNTs)作为一种新型碳纳米材料具有比表面积大、催化性能好等特点。本文采用循环伏安法,研究了盐酸硫利达嗪(TR)在HCNTs修饰玻碳电极(HCNTs/GCE)上的电化学行为。HCNTs/GCE与裸玻碳电极及碳纳米管修饰的玻碳电极相比,对TR具有更强的催化氧化性能,其差分脉冲伏安法的峰电流与浓度在18.67~122.7μmol/L范围内呈良好的线性关系,检出限为5.120μmol/L。
Helical carbon nanotubes(HCNTs) as a novel carbon material have been prepared and the catalytic activity of the HCNTs-modified glassy carbon electrode(GCE) towards the electrooxidation of thioridazine hydrochloride(TR) has also been investigated. Comparing with the bare GCE and multi-wall carbon nanotubes (MCNTs) modified GCE, the HCNTs modified GC electrode has higher catalytic activities towards the oxidation of TR. The determination of TR was carried out successfully. The linear response range for TR was 18.67-122.7 μmol/L and the detection limit(S/N=3) was 5.12 μmol/L.
