EVALUATION OF SURFACE-AREA OF CARBON COMPONENT OF MODEL CARBON-SILICAADSORBENTS FROM ADSORPTION DATA OF P-NITROPHENOL FROM AQUEOUS-SOLUTIONS

Complex carbon-mineral adsorbents have become very attractive material s owing to their wide applicability. Determination of carbon deposit m orphology and topography is one of the most essential tasks. The paper presents the results of studies on texture and structure of a series of carbon-silica adsorbents (carbosils) differing in the carbon deposi t content (0.8-35.0% w/w) based on the data of gas and liquid adsorpti on as well as electron microscopy. The theoretical approach was also u sed to describe the complex adsorbent texture models. (C) 1998 Elsevie r Science B.V.
