毛细管电泳分离氟苯甲酸同系物
, PP. 994-998
Keywords: 氟苯甲酸,毛细管区带电泳,β-环糊精
Abstract:
建立了毛细管区带电泳分离测定10种氟苯甲酸同系物的方法。考察了缓冲溶液的组成添加剂浓度、酸度及分离电压等因素的影响。选定的分离条件为:分离电压为17kV,30mmol/Lβ-环糊精(β-CD)+22mmol/L硼酸盐缓冲溶液作为电泳缓冲液(pH8.80),检测波长为214nm。在上述条件下,10种氟苯甲酸同系物在7.5min内可完全分离,检出限为0.8～4.5mg/L;峰面积相对标准偏差(RSD)为0.3%～4.3%;回收率为88.9%～102.8%。本方法高效、快速、简便,有望应用于油田示踪剂中氟苯甲酸同系物的分析。
