摘要：Three kinds of hydrogel materials combining MOF-derived magnetic Fe/porous carbon (MagFePC) with sodium alginate (SA), polyacrylic acid (PAA) and agarose (AG) were prepared by different methods for removal of norfloxacin (NOR) antibiotics in simulated wastewater. After comparison, MagFePC/SA hydrogels synthesized by a titration forming method were found to have the advantages of simple preparation, good toughness, abundant pores and high Fenton activity. MagFePC/SA can effectively activate H2O2 to remove NOR under neutral conditions, and there was almost no leaching of iron ions, causing no secondary pollution to the environment. Mechanism study revealed that ·O2- and 1O2 were the main active species for the degradation of NOR pollutants, and cyclic experiments showed the materials still had good degradation ability after repeated cycles indicating good stability and reusability of the materials. More important, we built a simple automated wastewater treatment unit that can completely degrade a 5 mg/L NOR antibiotic solution at a flow rate of 2 mL/min. Current works showed that MagFePC/SA had the advantages of simple synthesis, outstanding degradability, excellent stability and eco-friendly reaction, which was a wastewater treatment material with good prospect for industrial application. ? 2021, The Authors.
