The sol-get method has been reported a useful techniques for synthesizing inorganic material HSS. In this study, the sol-gel process was used in two stages. In the first step, the hydrolysis of phenyltrimethoxysilane (PTMS) was carried out under acidic conditions. In the second step, the silane condensation proceeded under basic conditions and as a result the HSS were obtained. The obtaining HSS was treated with epichlorohydrin to carry out an epoxidation process (HSEPC). Then, HSEPC was functionalized by treatment with natural resin (gum arabic) and obtained HSEPCGUM. Gum arabic has GA-GP-GA-glycoprotein, hydroxyproline glucuronic acid and polysaccharides groups. Anionic and cationic dyes were adsorbed onto HSEPCGUM and values of absorbance was measurement by UV-Visible spectrophotometers. Adsorption isotherm experiments of adsorbed dyes on HSEPCGUM were performed at 35 degrees C with Freundlich, Langmuir and Dubinin-Radushkevich (DR) methods. Adsorption maximum capacity of HSEPCGUM (X-max) was obtained 100 mg/g for BB3. Before and after dye adsorption the structure characterization of adsorbent was done by SEM and FTIR analysis.
