摘要

In this paper, benzene adsorption isotherm and their hysteresis on two important local diatomites were determined at 25℃, ani their silicon hydroxyl group (SiOH) nunber was determined, their properties were reported, and the relationship between surface structure, surface SiOH number per nm2and adsorption isotherm with hysteresis was discussed. The specific surface was also calculated from the isotherms, and pore-size distribution was determined.
