摘要：
A method of on\|line ultrasensitive chemiluminescence detection with capillary electrophoresis for Co(Ⅱ) is reported. Using our newly developed capillary electrophoresis with chemiluminescence detection system and novel mixing mode of the reagents, the effects of field\|amplified sample injection on detection limits of metal ions were studied in detail. The sub\|fmol/L level(0.13 fmol/L, 1.6 ymol) detection of cobalt ions in ultradilute solution was performed. The separation of fmol/L level Co(Ⅱ) and trace amounts of Ni(Ⅱ) was performed successfully.
