摘要	This study demonstrated high-efficient dye adsorption for wastewater using MoS2-glue sponge as an easy-separative and regenerative adsorbent. Flower-like molybdenum disulfide (MoS2) nanopowders with rich polar edge sites were firstly synthesized by a facile one-pot hydrothermal method. Chemical and morphological features of MoS2 nanoflowers were then examined by XRD, XPS, SEM and TEM. Afterwards, different concentrations of the MoS2-glue sponges with easy separability were successfully fabricated by a convenient two-step dipcoating method. The adsorption performance was estimated by the removal of Rhodamine B (RhB) dyes. The results proved that the maximum adsorption capacity of MoS2-glue sponge was 127.39 mg RhB/g product in 60 min. The RhB uptake behaviors can be well described by the Sips isotherm model and pseudo-second-order kinetic model, indicating a multilayer and chemical adsorption process. The adsorption mechanism proposed that the zwitterionic RhB molecules in aqueous solution would aggregate on the surface of negative charged MoS2 in a head-to-tail way through electrostatic interaction. Furthermore, RhB dyes could desorb easily from MoS2-glue sponges when changing the polarity of solvent and the reusability experiment showed that the MoS2-3% glue sponge could be reused for 15 times with above 85.8% of the adsorption capacity retained. Thus, the novel MoS2-glue sponge is considered as a competitive adsorbent for treatment of dyestuff waste water.
