| 英文摘要 | Spent bleaching earth (SBE), a waste by-product produced from the bleaching step of edible oil by montmoril-lonite clays (bleaching earth), causes serious public health and environmental problems. Accordingly, in this study, SBE was pyrolyzed to yield mineral carbon materials (SBE@C) and cobalt oxide (Co3O4) was loaded to improve the active site of those materials. Due to the carrier function of SBE@C, ultra-fine Co3O4 quantum dots (QDs) (2-6 nm) were homogeneously and robustly immobilized onto SBE@C. The obtained adsorbent exhibited high regeneration performance and an outstanding adsorption capacity (253.36 mg/g). It can be attributed to the surface complexation of cobalt with TC being the dominant process contributing to adsorption behavior. Further, Co3O4 QDs-SBE@C still maintained adequate sorption capacity at a broad range of pH values and in the presence of co-occurring ions. These results suggested the significant application potential of SBE and demonstrated the efficiency of using Co3O4 QDs-SBE@C for wastewater remediation. |
