摘要：
Adsorption effects on the retention of hydrocarbons were investigated in gas-liquid-solid chromatography using modified alumina beads, preheated at 1150 and 1200 degrees C, coated with diphenyl phthalate as column packings. At a column temperature above the melting point of diphenyl phthalate, the same method as used in a previous study could be applied for interpreting the solute retention behaviour. At a column temperature below the melting point of the stationary phase, the retention mechanism could be successfully understood by considering that some adsorption equilibria took part in solute retention on the basis of the distribution of diphenyl phthalate in a solid form on the modified alumina surface.
