摘要
目的建立测定废水中邻硝基苯酚(o-NP)含量的极谱法。方法测定待测样品及标准样品与镉离子、β-环糊精(-βCD)形成包合物的峰电流。结果平均回收率为99.4%,RSD为0.19%。结论本法准确、稳定、简便,适于推广。
Objective： To establish a osilloplaromethod for the determination of o-nitmphenol （o-NP） in waste water. Methods： The biggest current of inclusion complexes which were made of pilot sample （or standard sample） and cadmium ion with β-cyclodextrin was determined. Results： The average recovery rate was 99.4% （n = 5）, and RSD was 0.19%. Conclusion： The method is simple, reliable and accurate.
