摘要：

Thermogravimetric analysis was applied to the characterization of the porosity of silica gels. Thermal desorption of benzene, n-heptane, acetone and diethyl ketone was investigated. Characterization was performed also by using nitrogen adsorption/desorption measurements. For different wetting liquids the results of both methods are compared.
