Adsorption process of methyl orange dye onto mesoporous carbon material-kinetic and thermodynamic studies

► The prepared CMK-3 is a good replica of its template SBA-15. ► Adsorption process was fast enough, and 60 min contact time is sufficient. ► CMK-3 is an excellent adsorbent for dye removal. ► It is a good replacement of commercially available carbons.
