摘　　要：基于硝基苯在银基汞膜电极上-0.675V(vs.Ag/AgCl)处有一良好的伏安峰,该文采用方波伏安法对苯胺生产线废水中的硝基苯进行了测定。分析结果表明,方波伏安峰的电流峰值与硝基苯浓度在1.0～300mg/L范围内呈很好的线性关系,检出限为0.35mg/L。方法简便、快速,灵敏度高,尤其适用于不同水体系中硝基苯检测。A method was developed for the determination of nitrobenzene in waste water by square wave voltammetry using silver based mercury membrane electrode. Through experiments, we have selected the best experiment parameters. The experiment results indicate that there is a very good square wave vohammetrie peak at - 0.675 V （vs. Ag,/AgCl）. In the range of 1.0 - 300 mg/L, the concentration of nitrobenzene and the square volammetry peak height shows a satisfying linear relationship, and the detection limit is 0.35 mg/L. This method is simple, fast, sensitive and accurate, especially be suitable for the test of nitrobenzene in different water system, and have been applied in Jiangsu Shuangliang Group for the waste water monitoring on the aniline production line.
