PG - 224-231 LID - S0144-8617(17)30920-7 [pii] LID - 10.1016/j.carbpol.2017.08.059 [doi] AB - Organic micropollutants in aquatic environment such as plasticizer, pesticide and pharmaceuticals, have posed a serious threat to human health and are emerging as a great challenge to humanity. Traditional water treatment techniques fail to achieve high removal efficiency for low concentration of organic micropollutants. Here we demonstrate a water-insoluble crosslinked beta-cyclodextrin (beta-CD) polymer able to remove a broad-spectrum of organic micropollutants from water by rapid adsorption. A family of beta-CD polymers (beta-CDPs) were synthesized by nucleophilic aromatic substitution of beta-CD hydroxyl groups and 4,4'-difluorodiphenylsulfone. The beta-CDPs were used to adsorb various organic micropollutants in water by static or dynamic adsorption process. It was found that more than 99% micropollutants in water were removed by flowing the feed water through the column of beta-CDPs. The results of static adsorption experiments indicated the adsorption process was fast and the adsorption capacity was very high (the maximal value was 113.0mg of bisphenol A per gram of beta-CDP). The adsorption process was fitted well with the quasi-second-order kinetics and the Langmuir isothermal adsorption model, suggesting that it is mainly a chemical adsorption of monolayer. The water-insoluble characteristic of the beta-CDPs is convenient for their separation from the treated solution after adsorption saturation for regeneration and reuse. The adsorption ability of beta-CDPs was kept nearly unchanged after five filtration-regeneration cycles. CI - Copyright (c) 2017 Elsevier Ltd. All rights reserved.
