The voltammetric response of nitrogen dioxide in aqueous sulfuric acid using an edge plane pyrolytic graphite electrode has been explored and contrasted with that from basal plane pyrolytic graphite, glassy carbon or boron-doped diamond electrodes. Edge plane graphite electrode is found to produce an excellent voltammetric signal in comparison with other carbon-based electrodes exhibiting a well-defined analytically useful voltammetric redox couple in 2.5 M sulfuric acid which is absent on the alternative electrodes.
利用边缘平面热解石墨电极,研究了二氧化氮在硫酸水溶液中的伏安响应,并与基平面热解石墨电极、玻碳电极或掺硼金刚石电极的伏安响应进行了对比。结果发现,与其他碳基电极相比,边缘平面石墨电极能产生优异的伏安信号,在2.5 M硫酸中呈现出定义明确且对分析有用的伏安氧化还原对,而其他电极则没有这种现象。
