▎ 摘　　要

The Co(OH)(2)/reduced graphene oxide hybrids (Co(OH)(2)/rGO) was prepared and used as catalyst to enhanced heterogeneous activation of Oxone for the decomposition of Levofloxacin (LVF). The Co(OH)(2)/rGO composites with different Co(OH)(2) loading have been successfully synthesized, where the sample contain 20% Co(OH)(2) exhibited superior activation, attributing to the synergistic effect between Co(OH)(2) and rGO. Meanwhile, the effects of some important reaction parameters on the decomposition of LVF by Co(OH)(2)/rGO/Oxone process were investigated. The results indicated that the decomposition rate of LVF(>94.5%) was increased with the increasing of Oxone concentration, and 20% Co(OH)(2)/rGO dosage neutral pH. Moreover, the Co(OH)(2)/rGO catalyst showed high activity and stability during the repeated experiments. (C) 2018 Elsevier B.V. All rights reserved.
