提出了在碳纳米管 (CNT) 电极上存在抗坏血酸 (AA) 的情况下选择性电化学测定食品中芦丁的方法。 CNT电极显示出芦丁检测的理想特性，即对目标的高且明显的响应电流、小基极电流和高再现性/重复性。在循环伏安法中，观察到源于芦丁中儿茶酚基团氧化的显着电流峰。当[AA]/[芦丁]质量比达到2.0时，CNT电极选择性测定芦丁的浓度范围为0.024~4.0 mg ml−1。
The selective electrochemical determination of rutin in the presence of ascorbic acid (AA) in food at the carbon nanotube (CNT) electrode is presented. The CNT electrode shows ideal characteristics for rutin detection, which are high and distinct response current towards a target, a small base current and high reproducibility/repeatability. In cyclic voltammetry, the prominent current peak that originated from catechol group oxidation in rutin is observed. The performance of the selective determination of rutin at the CNT electrode is in the concentration range of 0.024–4.0 mg ml−1 when the mass ratio of [AA]/[rutin] is up to 2.0.
