The texture and composition of the samples were characterized by XRD, N2 Revised 4 February 2015 adsorption, FE-SEM, TEM, FT-IR, and 27Al MAS NMR. As a catalyst, the effects of ethyl acetate to the diameter Accepted 8 February 2015 and sphericity of the samples have also been investigated. The results show that the sample Al-MCM-41-10 Available online 4 March 2015 prepared at the amount of ethyl acetate value of 10 mL displays the largest BET surface area (525.0 m2 /g) and Keywords: pore volume (0.71 cm3 /g). Using this material as adsorbent for methylene blue (MB) removal, the adsorption Mesoporous adsorbents
