外文摘要：Here, molybdenum sulfide (MoS2) was characterized and its performance as an adsorbent for Co(II)/Ni(II) removal from water was estimated in batch experiments. The nanomaterial exhibits thin-layered structure and contains numerous hydroxyl groups. High pH enhanced Co(II)/Ni(II) sorption, while ionic strength had no effect. The chemical sorption between the binding sites of MoS2 and Co(II)/Ni(II) limited the rate. The Freundlich isotherm correlated better than Langmuir isotherm. The maximum sorption capacity for Co(II)/Ni(II) was 370.10/375.94 mg center dot g(-1), obviously exceeding other adsorbents. Both adsorptions were endothermic and spontaneous processes. This study indicates the intrinsic value of MoS2 in removing heavy metals from water.
