| 摘 要： | 研究了连续激光照射对抗坏血酸电氧化的影响。发现激光照射能使氧化电流显著增加 ,起始氧化电位明显减小。对不同材料的电极 ,这些变化存在差异。在玻璃碳电极 (GCE)、石墨电极和金电极上 ,电流分别增加了 5 71倍 ,2 14倍和 3 0 2倍 ;起始氧化电位在前两种电极上都减小了 5 0mV ,而在金电极上则降低了 2 5 0mV。分析认为 ,激光照射产生的热效应是引起氧化电流及电势变化的主要因素。同时 ,激光照射也可能使电极表面在一定程度上被活化 ,从而加快了电极反应的进行。

| Abstract: | Influence of electro-oxidation of ascorbic acid was investigated under CW laser irradiation. It was found that oxide current dramatically increased and initial oxide potential evidently decreased with laser irradiation. The current increased by 5.71, 2.14, 3.02 times for GCE, graphite electrode and Au electrode, respectively. Initial oxide potential decreased by 50 mV for both GCE and graphite electrode, by 250 mV for Au electrode. The thermal effect proceed by laser irradiation is mainly factor to cause the changes of oxide current and potential, at the same time, electrode surface is likely activated to a certain extent due to laser irradiation accelerating electrode reaction. |
