Abstract:
Ordered mesoporous materials, because of its specific high surface area, a large pore size and uniform pore size distribution, reflects its more obvious advantages in the adsorption. The study describes the adsorption behavior of disinfection by-products such as dichloroacetic acid from aqueous solution using ordered mesoporous carbon in different pore size distribution. Ordeded mesoporous carbon was synthesized via the evaporation induced self-assembly method with Pluronic F127 as a template and phenolic resin as a carbon source and employed to evaluate the effects of initial concentration, contact time, pH and temperature on the removal of dichloroacetic acid in batch experiments. In this study, the method of controlling the aperture of ordered mesoporous carbon is changing the polymerization time of phenolic resin which can change the relative molecular weight and the length of molecular chain of phenolic resin. The samples were characterized by scanning electron microscopy (SEM) and N2 adsorption-desorption. These analyses reveal that the mesoporous carbon have ordered structure. The experimental results indicated the ordered mesoporous carbon in different pore size distribution showed significant differences in the adsorption of dichloroacetic acid and their adsorption capacities are 5.80, 20.62, 16.24 mg/g, respectively.
