Abstract:Facing increasing PPCPs pollution in source water, carbamazepine (CBZ) as typical pollutant was studied to be removed by powdered activated carbon with magnetic resin pre-treatment. Freundlich model was more appropriate to describe the adsorption pattern of CBZ in aqueous solution. The adsorption kinetics of CBZ could be well described with pseudo-first-order kinetic equation, whereas pseudo-second-order kinetic equation was better for the description of the adsorption process more than 1h. 200~300mesh PAC showed the largest adsorption capacity and fastest adsorption speed to CBZ. In the study of simulated source water treatment, compared with using PAC alone, the combination of magnetic resin and PAC improved the removal efficiency of DOC by 40.64%, UV254by 41.27%, CBZ by 14.72% respectively. The results of this research indicate that there is a kind of cooperative effect between magnetic resin and PAC on removing organic pollutants in water, which results in the enhanced removal efficiency of CBZ by PAC adsorption with magnetic resin pre-treatment.
