| 英文摘要 | The rate equation of solute migration for a gas-solid chromatography was derived from Maxwell distribution of energy and the principle of equipartition of energy. Different from two-phase distribution ratio being used to explain the retention time of solute in plate theory, the retention time was explained with the activation energy of migration from a new and kinetic viewpoint. According to the derivation of the rate equation for solute migration, the activation energy of migration related to the kinetic energy of translation, rotation and vibration. Temperature observably influenced the activation energy of migration. Separation mechanism of gas-solid chromatography was based upon different solutes having different functions of physical adsorption on the stationary phase. This property could be the cause of the activation energy of migration being different from reaction activation energy in nature. The activation energy of migration for alkane homolog increased with carbon number. To investigate the mechanism of gas-solid chromatography was attempted from a kinetic viewpoint, in order to provide some ideal at understanding chromatography process. 漏2009 IEEE. |
