Abstract
Ordered mesoporous carbon CMK-3 (OMC) have been synthesized using mesoporous SBA- 15 silica as template and modified with cobalt carbonate. Morphologies and surface texturing of materials were characterized by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM) and N2 adsorption-desorption isotherms. The cobalt modified ordered mesoporous carbon were found to have a surface area of 490.06m2/g and pore volume of 0.42cm3/g. The adsorption behavior of 1, 10-Phenanthroline (OP) and 2, 2'-bipyridine (BP) on cobalt modified ordered mesoporous carbon (Co+2-OMC) were studied in aqueous system. The parameter such as temperature, contact time and initial OP and BP concentrations was investigated. Batch adsorption studies demonstrate that the cobalt containing CMK-3 has significant capacity for adsorption of OP and BP from aqueous solution. The adsorption processes of OP and BP are tested with langmuir and freundlich isotherm models. According to the langmuir isotherms, the maximum adsorption capacities of OP and BP on Co+2-OMC were 595 and 500 mg/g, respectively.
