| 摘 要： | 采用电化学还原法对溶液中一氧化氮（ＮＯ）进行测定，研究对比了电化学氧化和电化学还原对ＮＯ检测的选择性和灵敏度，同时研究了工作电极表面修饰膜厚度、工作电极在被测溶液中的吸附时间，扫描速度对峰电流及峰电位的影响，证明电化学还原法选择性好，方法检出限为６μｍｏｌ／Ｌ，线性范围１０￣８００μｍｏｌ／Ｌ。

| Abstract: | n this paper, NO in aqueous solution was determined by
electrochemical reduction with a threeelectrodesystem. The selectivity and sensitivity of
electrochemical oxidation and electrochemical reduction were compared. The experiment proved
that the latter mothed is more selective than the former. The detection limit is 10mol/L. |
