| 英文摘要 | the migration mechanism of ionizable compounds in capillary electrochromatography (cec) is more complicated than in high performance liquid chromatography (hplc) due to the involvement of electrophoresis and the second chemical equilibrium. the separation mechanism of ionizable compounds in cec has been studied theoretically. the electrochromatographic capacity factors of ions (k *) in cec and in the pressurized cec are derived by phenomenological approach. the influence of ph, voltage, pressure on k* is discussed. in addition, the k * of weak acid and weak base are derived based on acid-base equilibrium and the influence of ph on k * is studied theoretically. |
