摘　　要：采用正交设计法对胶束毛细管电泳中的优化分离条件进行了考察 ,研究了改性剂、十二烷基硫酸钠 ( SDS)及 β-环糊精 ( β-CD)浓度和 p H值几个参数对分离的影响。优化结果表明 ,在 3 0 min内 ,性质相近的邻、对、间 -硝基甲苯及 2 。The applicability of orthogonal array designs(OADs)for the optimization of separation in micellar electrokinetic capillary chromatography was investigated. The affecting factors including pH, concentrations of SDS, CD and methanol (CH 3OH) on the quality of the separation were studied. Optimum separation conditions were obtained, which gave good resolution of the components of o,m,p-nitroluene and 2,4-dinitrotoluene within 30 min.
