摘要:
为提高水中抗生素类有机污染物降解的稳定性，采用原位合成法将沸石咪唑酯骨架材料ZIF-8与氧化石墨烯（GO）进行合成，并制备成宏观金属有机骨架（MOFs）气凝胶ZIF-8/GO。通过电子扫描电镜（SEM）、热重分析仪（TG）、傅里叶变换红外光谱仪（FTIR）、X射线衍射仪（XRD）、气体吸附分析仪等表征手段分析ZIF-8/GO气凝胶的理化性能。结果表明，ZIF-8/GO保持了GO和ZIF-8单体各自稳定的晶体结构，二者结合后有较高的孔隙率和吸附性能。当吸附时间为12 h、温度为40 ℃、pH为6、污染物初始浓度为80 mg/L时，ZIF-8/GO对环丙沙星和四环素的吸附量达到最佳，分别为160.26和173.86 mg/g。吸附过程更符合伪二级动力学（PSO）模型和Langmuir等温模型，ZIF-8/GO吸附抗生素的过程为单层吸附。在循环使用次数达到5次时，对抗生素的吸附量仍大于100 mg/g，可见，ZIF-8/GO复合气凝胶有高效的吸附能力和循环再生能力。
Abstract:
To enhance the stability of degrading antibiotic organic pollutants in water, macroscopic metal-organic frameworks (MOFs) aerogel, ZIF-8/GO, was synthesized via an in-situ method using zeolitic imidazolate framework-8 (ZIF-8) and graphene oxide (GO). The physicochemical properties of the ZIF-8/GO aerogel were characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and gas adsorption analyzer. The results showed that ZIF-8/GO retained the stable crystal structures of both GO and ZIF-8 monomers. The combination of the two materials resulted in high porosity and excellent adsorption performance. Under optimal conditions—an adsorption time of 12 hours, a temperature of 40 ℃, a pH of 6, and an initial pollutant concentration of 80 mg/L—ZIF-8/GO achieved maximum adsorption capacities of 160.26 mg/g for ciprofloxacin and 173.86 mg/g for tetracycline. The adsorption process followed the pseudo-second-order kinetic (PSO) model and the Langmuir isotherm model, indicating monolayer adsorption. After five adsorption-desorption cycles, the adsorption capacity for antibiotics remained above 100 mg/g, demonstrating that the ZIF-8/GO composite aerogel possessed high adsorption capacity and good recyclability.
