Modeling of syringic acid adsorption onto (3-aminopropyl)triethomilane-modified mesoporous silica
Adsorptive properties of (3-aminopropyl)triethoxysilane-modified SiO2 towards syringic acid were detd. Non-linear fitting anal. was employed to est. Freundlich, Langmuir, Jovanovic, Dubinin-Astakhov and Redlich-Peterson isotherm parameters. The max. adsorption capacity (Dubinin-Astakhov model) was 125.0 mg/g. The adsorbent showed adsorption efficiency ca. 90% at the lowest initial phenolic acid concn.
