Preparation of Fe/Zn-MOFs by Microwave-Assisted Ball Milling and Removal of Levofloxacin Hydrochloride and Congo Red

In this study, Fe/Zn-metal–organic frameworks (Fe/Zn-MOFs) were synthesized via microwave-assisted ball milling and characterized via Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, and nitrogen adsorption–desorption analysis. Fe/Zn-MOFs were highly effective in removing common organic pollutants. Experimental results revealed that Fe/Zn-MOFs exhibited excellent removal efficiencies, with maximum rates of 95.2 and 99.3% for levofloxacin hydrochloride (LH) and Congo red (CR), respectively. Additionally, Fe/Zn-MOFs exhibited remarkable adsorption capacities for CR and LH, with maximum values of 2806.5 and 77.8 mg/g, respectively. These results highlight the potential of Fe/Zn-MOFs as an effective material for the removal of organic pollutants.
