title: Preparation and application of trimethylamine amination polychloromethyl styrene nanolatex coated capillary column for the determination of bromate by field-amplified sample stacking open-tubular capillary electrochromatography.
abstract: A new trimethylamine amination polychloromethyl styrene nanolatex (TMAPL) and TMAPL coated capillary column (ccc-TMAPL) were successfully prepared. The TMAPL coating was characterized with reversed steady EOF values of ca. -16.8 × 10(-5) cm(2) V(-1) s(-1) . It was applied to establish open-tubular (OT) CEC and field-amplified sample stacking (FASS) OT-CEC methods for the determination of bromate in tap water. Compared to OT-CEC, the LOD with FASS-OT-CEC was improved from 80 to 8 ng/mL. The developed FASS-OT-CEC method was practically used for the analysis of bromate in tap water samples with recoveries ranging from 93.6 to 103.5%.
