Nano structured aluminosilicates with different concentration of Al and Si were synthesized by alkoxides precursors and sol–gel methods. The chemical analysis, chemical structure, surface morphology, surface area, and porous structure of the synthesized aluminosilicates were characterized. The aluminosilicates were used as adsorbents in batch adsorption tests for removing phenol from water. The results showed that Langmuir isotherm had better fitting with experimental data than Freundlich isotherm. The results also showed that increasing in the silica concentration of the aluminosilicate improved the phenol adsorption due to ionic nature of SiO bond. Ortho aminophenol and 2-naphtol adsorptions were also investigated and their maximum molar adsorption capacities were close to each other.
