| 摘 要： | 报道了采用氯乙酸甲酯作为液-液半微萃取溶剂与胶束电动色谱耦联，通过萃取剂柱上分解来富集分离中性化合物的方法。选取烷基苯酮类（C8, C10 和C11）作为模型化合物，将水中的烷基苯酮类化合物通过液-液半微萃取进入氯乙酸甲酯相中，氯乙酸甲酯相直接进入胶束电动色谱中分离。对于苯乙酮、苯丁酮和苯戊酮的检出限分别为50，50和100 μg/L（S/N≥3），三者的富集因子达到63～151。本方法只需要有一个毛细管电泳仪而无须特殊设备，省时且操作简便。因此，有很大的潜力用于实际环境样品分析。

| Abstract: | This paper reports the use of methyl chloroacetate(MCA) as an extraction solvent for coupling liquid-liquid semimicroextraction(LLsME) with micellar electrokinetic chromatography(MEKC) through on-capillary decomposition for the separation of neutral compounds with concentration enhancement.Alkylphenones butyrophenone,valerophenone and acetophenone were chosen as modeling compounds.Aqueous samples of the alkylphenones were extracted by LLsME into MCA.The organic phase was directly subjected to separate by ME... |
