In this study, a novel adsorbents, molybdenum disulfide-graphene oxide (MoS2–GO) composites, is prepared by one-step hydrothermal method and used for U (VI) adsorption. SEM, XRD, FT-IR, BET and XPS results show that the MoS2 layers grow on the surface of graphene oxide layers, forming MoS2–GO composite structure. The specific surfaces area of MoS2–GO composite (5.5 m2/g) is higher than that of MoS2 (2.3 m2/g). Batch adsorption experiments indicate that the adsorption process of uranium (VI) on MoS2–GO conforms to the quasi-second-order kine...
