摘要

环丙沙星（CIP）的滥用和处置导致其在全球水体中被检出，给公众健康和水环境带来巨大风险。本文通过一锅水热法合成了（Zn-Al） LDHs修饰的3D还原氧化石墨烯纳米复合材料（(Zn-Al) LDHs/3D- rgo）。在3D-rGO表面高度分布的（Zn-Al） LDHs薄片赋予了所得的（Zn-Al） LDHs/3D-rGO具有优异的CIP吸附性能。吸附结果表明，用Temkin等温模型和拟二级动力学模型可以很好地解释吸附过程。在响应面法优化的条件下，CIP的最大吸附量为20.01 mg·g−1。探讨了共存离子对CIP吸附的抑制作用。吸附机理可能归因于π−π相互作用、氢键、静电和表面络合作用。再生试验表明，所制备的三维多孔材料具有明显的可回收性。所得的（Zn-Al） LDHs/3D-rGO具有去除实际废水中CIP的巨大潜力。

Adsorption of ciprofloxacin on (Zn-Al) LDHs modified 3D reduced graphene oxide: Response surface methodology, adsorption equilibrium, kinetic and thermodynamic studies

The indiscriminate use and disposal of ciprofloxacin (CIP) have led to its detection in water globally, which pose a huge risk to public health and water environment. Herein, (Zn-Al) LDHs modified 3D reduced graphene oxide nanocomposite ((Zn-Al) LDHs/3D-rGO) was synthesized through a feasible one-pot hydrothermal method for CIP removal. The highly distributed (Zn-Al) LDHs flakes on the surface of 3D-rGO endow the resulted (Zn-Al) LDHs/3D-rGO with an excellent adsorption performance for CIP. The adsorption results showed that the adsorption process could be well interpreted by Temkin isothermal model and the pseudo second-order kinetics model. The maximal adsorption capacity of 20.01 mg·g⁻¹ for CIP could be achieved under the optimal conditions optimized by response surface methodology (RSM). The inhibitory effect of co-existing ions on CIP adsorption were also discussed. The probable adsorption mechanism might be ascribed to π−π interactions, hydrogen bonding, electrostatic, and surface complexation. Regeneration tests showed that the obtained 3D porous material also possessed pronounced recyclability. The obtained (Zn-Al) LDHs/3D-rGO holds a great potential for removal of CIP from actual wastewater.
