摘要: Abstract Temperature programmed desorption (TPD) is applied to the study of surface Aerosil. The resultant chromatograms differentiate between molecular water adsorbed on and various silanol groups that exist it. It found restored even though solid subjected temperatures at which its total removal would be expected. TPD method also allows heterogeneity shown, as well influence physisorbed dehydration Aerosil surface.
