▎ 摘  要

In the present study, we described a facile preparation of graphene oxide incorporated alginate hydrogel beads (SA/GO) and applied them in adsorbing organic pollutants in aqueous media. The results show that the incorporation of graphene oxide obviously decreased the pore size and swelling ratio of the hydrogel beads. The existence of the GO also significantly enhanced the adsorption capability of the SA/GO beads to various organic dyes, including heterocyclic dye, indigo dye, anthraquinone, and azo dye. Besides, the SA/GO beads show promising adsorption capability to the bisphenol A (BPA), a toxic chemical which could cause endocrine disruption. The adsorption isotherm and kinetic of the SA/GO beads were also studied in detail. The present study indicates that the SA/GO beads are a type of effective absorbent for various organic pollutants which have the potential to be applied in water purification fields.
