Article Title: Surface Textural Characteristics of the Prepared and Modified Silica Gel Surfaces
by Ashraf Yehia El-Naggar

The objective of this study is to relate structural, textural and surface characteristics of silica gel surfaces to their various modifications. These modifications include calcination, hydrothermal treatment, coating and bonding with polyethylene glycol (Carbowax-20M) in addition to double modifications to obtain silica samples of different surface characteristics to cover many applications in different fields. Nitrogen adsorption was studied for monitoring the changes in textural properties of the parent and modified silica. The data indicates the widening in the pore accompanied the calcination and bonding with polymer. other aim of this work is of prime importance not only for understanding how modification is related to the changes in these properties but also to the change in the performance of these silica surfaces as adsorbents and chromatographic stationary phases. Surface chemistry and nitrogen adsorption must be taken into account in the decision-making process of choosing a selective adsorbent for each problem.
Keywords: structural, surface characteristics, calcination, hydrothermal treatment, coating and bonding.
