Abstract
This paper reported, the effect of different type of surfactants on the adsorption of Cd(II) on ordered mesoporous carbon was investigated using cationic, anionic and non-ionic surfactant. The structural order and textural properties of the mesoporous adsorbents was studied by XRD and nitrogen adsorption. Adsorption experiments were conducted in batch mode with the variables such as amount of agitation speed, contact time, temperature, initial solution concentration and solution pH. The Cd(II) removal for cationic surfactant cetylpyridinium chloride (CPC), non-ionic surfactant Triton X-100 (TX), anionic surfactant sodium dodecyl sulfate (SDS) modified mesoporous carbon and unmodified mesoporous carbons were found to be 94.5%, 88.4%, 84% and 68%, respectively. The sorption data were correlated better with the Langmuir adsorption isotherm than Freundlich isotherm.
