cobalt functionalizedorderedmesoporous carbon as effectiveadsorbent forremoval oforganic pollutants fromaqueousmedia

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 werecharacterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and n2 adsorption-desorptionisotherms. the cobalt modified ordered mesoporous carbon were found to have a surface area of 490.06m2/gand 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. theparameter such as temperature, contact time and initial op and bp concentrations was investigated. batchadsorption studies demonstrate that the cobalt containing cmk-3 has significant capacity for adsorption ofop and bp from aqueous solution. the adsorption processes of op and bp are tested with langmuir andfreundlich isotherm models. according to the langmuir isotherms, the maximum adsorption capacities of opand bp on co+2-omc were 595 and 500 mg/g, respectively.
