| Abstract: | A MWCNTs/PPy/PMo12 modified pencil graphite electrode(PGE) was developed.The capillary electrophoresis with amperometric detection(CE-AD) method was employed for the determination of bromate(BrO-3)without the interference of chlorate(ClO-3)and iodate(IO-3)in drinking water with the MWCNTs/PPy/PMo12/PGE electrode.The effects of several factors on CE-AD were investigated.Under the optimum conditions,bromate could be well separated in the capillary at the working potential of-0.24 V,separation voltage of-15 kV... |
