摘要 目的 制作碳纳米管修饰电极 ,并研究己烯雌酚在该电极上的电化学行为。方法 循环伏安法及线性扫描伏安法。结果 与裸玻碳电极 (GCE)比较 ,多壁碳纳米管修饰电极能显著提高己烯雌酚的氧化峰电流并降低其氧化电位。峰电流与己烯雌酚浓度在 1× 1 0 -8~ 2× 1 0 -6mol·L-1 有良好的线性关系 ,检测限为 2 5× 1 0 -9mol·L-1 。 1×1 0 -6mol·L-1 己烯雌酚溶液的相对标准偏差为 2 9%。结论 多壁碳纳米管对己烯雌酚的电化学氧化有明显的催化作用。 Aim To fabricate multi wall carbon nanotube (MWNT) modified electrode and study the electrochemical behaviors of diethylstilbestrol at the MWNT modified electrode. Methods Cyclic voltammetry and linear sweep voltammetry. Results The oxidation peak current of diethylstilbestrol increased remarkably and the peak potential shifted negatively at the MWNT dihexadecyl hydrogen phosphate (DHP) modified glassy carbon electrode(GCE), in contrast to that at the bare GC electrode and DHP modified GC electrode. ...
