【Abstract】 The separation of two-component mixture composed of TiO2 and Al2O3 nanoparticles suspended in carbonate buffer solution was achieved by capillary electrophoresis with contactless conductivity detection. The effects of variety, concentration and pH of running buffer solutions on separation were investigated. The effects of amptitude and frequency of exitation signal on signal-to-noise ratio were also studied. Under optimized conditions, the complete separation of nanoparticles of TiO2 and Al2O3 were accomplished within 8 min.更多还原
