英文摘要C-12-alkyl bonded zirconia stationary phase was prepared for packing capillary electrochromatography (CEC). The influence of mobile phase on electroosmotic flow and the stability of the packing CEC column were systematically investigated. And the effects of organic modifier contents and pH on the retention of neutral and basic compounds were studied. The stability of the C-12-ZrO2 packing CEC column was satisfactory between pH 3 and 11.7. The strong interaction between the phosphate buffer and the zirconia surface can give the better stability than that of the traditional alkyl bonded silica stationary phase under low organic concentration. The CEC column can be applied in a wider pH range of mobile phase, in which the surface of the stationary phase having absorbed phosphate can provide enough electroosmotic flow. These advantages have greatly broadened the applications in CEC.
