Highly ordered mesoporous structure

In the present paper, the synthesis of Fe-MCM-41 with high iron content and highly ordered mesoporous structure was performed. The adsorption isotherms of As(III) and As(V) over Fe-MCM-41 were also presented.

The adsorption of phenol over MCM-41 prepared from rice husk silica was investigated. MCM-41 material (RH-MCM-41) was synthesized using sodium silicate prepared from rice husk as a silica source and cetyltrimetylammoniumbromide (CTAB) as a surfactant with the following gel composition: 1SiO2: 0.106CTAB: 0.03NaOH: 150H2O. The obtained material was characterized by XRD and BET. RH-MCM-41 exhibits high surface area and highly ordered hexagonal mesoporous structures. The adsorption of phenol over RH-MCM-41 fit well to both Langmuir and Freundlich isothermers.
