【 摘 要 】

In this study, surface energy of natural zeolite was investigated using inverse gas chromatography (IGC). Purified zeolite was prepared from natural zeolite applying decantation and centrifugation process together. For IGC studies, retention time of n-octane, n-nonane and n-decane were measured at infinite dilution conditions, between 250 and 280 °C. Dispersive component of the surface energy (γdS)of purified zeolite was calculated. γdSvalues calculated using Schultz et al methods decrease with temperature.
