摘要

研究了中性鲁米诺溶液在多壁碳纳米管(MCNTs)、酸化碳纳米管、酸化并煅烧的碳纳米管修饰电极上的电致化学发光。结果表明,由于酸化后碳纳米管表面羧基含量增多,从而对鲁米诺的电致化学发光(ECL)信号具有明显的增强作用。并讨论了电位扫描速度、pH值和支持电解质等因素对鲁米诺在酸化碳纳米管修饰电极上电致化学发光信号的影响情况。
        Electrogenerated chemiluminescence of luminol was comparatively studied at multi-walled carbon nanotubes(MCNTs),acidified MCNTs,acidified and burnt MCNTs modified glassy carbon electrode in neutral solution,respectively.The results revealed that the acidified MCNTs,which contained a large amount of carboxyl groups,could enhance luminol ECL significantly.Some impact factors,such as potential scan rate,pH,supporting electrolytes,which might influence luminol ECL at the acidified MCNTs modified electrode,were also investigated.
