| 摘 要： | 以7-CD为毛细管电泳手性选择剂，对苯氧羧酸类除草剂对映体的分离进行了研究。考察了手性选择剂的种类、7-CD浓度、SDS浓度、背景电解质浓度、pH值等对分离的影响。结果发现，选择30mmol·L11rCD＋100mmol·L11SDS＋75mmol·L-1H3P04作为电泳缓冲体系（pH值2．O），2，4-滴丙酸、2，4，5-滴丙酸、2-（3-氯苯氧基）丙酸对映体完全分离，2-（4-氯苯氧基）丙酸、2-苯氧基丙酸对映体部分分离，分离度分别为3．42、8．27、2．83、0．89、0．50。

| Abstract: | The chiral separation of phenoxy carboxylic acid herbicides enantiomers by capillary electrophore- sis was studied with ）,-CD as a novel chiral selector. The influences of the kinds of chiral selector, the concentra- tion of ·-CD,SDS and the background electrolyte,and the pH value were investigated. The result showed that using the optimum buffer system with pH value of 2.0 consisting of 30 mmol· L-1 7-CD,100 mmol· L-1 SDS and 75 mmol · L-1 H3 PO4, the enantiomers of 2,4-dichlorophenoxy propionic acid, 2,4,5-trichlorophenoxy pro- pionic acid,2-（3-chlorophenoxy） propionic acid could be fully separated and the enantiomers of 2-phenoxy pro- pionic acid and 2-（4-chlorophenoxy） propionic acid could be partly separated. Their separation degree were 3.42,8. 27,2. 83,0.89,0. 50,respectively. |
