The Electrocatalytic Oxidation of Nitric Oxide at Carbon Black Microelectrode Modified by Cobalt(II) Complex with N-salicylidene Glutamic Acid

研究了水杨醛谷氨酸合钻修饰碳黑微电极的制备方法和修饰电极对一氧化氮的电催化氧化性能．实验结果表明．在pH6．80的磷酸盐中，测定NO的线性范围为6．0×10^-8-2．0×10^-5mol／L；检出限（3σ）为1．0×10^-8mol／L．

In this paper, the preparation and electrochemical characteristics of carbon black microelectrode modified by cobalt （Ⅱ） complex with N-salicylidene glutamic Acid are studied. In pH 6.80 phosphate buffer solution （PBS）, the linear range for determining NO is 6.0×10^-8-2.0×10^-5mol/L, the detection limit （3σ） is 1.0×10^-8mol/L.
