摘要： Based on the mussel-inspired adhesive interface (Fe3O4-g-C3N4@PDA), a novel bionic metal-organic framework (Fe3O4-g-C3N4-PDA@MIL-101) was successfully prepared. The composite featured a high specific surface area and a multi-microchannel structure, as well as strong thermochemical stability. The structural property of Fe3O4- g-C3N4-PDA@MIL-101(Fe) was characterized, and the results indicated that Fe3O4, PDA, and MIL-101(Fe) were uniformly coated on the g-C3N4 surface. The adsorption and desorption of organophosphorus pesticides with Fe3O4-g-C3N4-PDA@MIL-101(Fe) were evaluated by batch experiments. This composite showed high adsorption efficiency and selective removal of coralox, phosalone, and chlorpyrifos. Under the optimal conditions, three organophosphorus pesticides were adsorbed from Chinese cabbage and green onion samples with Fe3O4-g-C3N4- PDA@MIL-101(Fe). The analytical method exhibited high sensitivity (LOD, 0.19-2.34 mu g/L; LOQ, 0.65-7.82 mu g/ L), excellent practicality, and good stability, suggesting that Fe3O4-g-C3N4-PDA@MIL-101 was an ideal candidate magnetic adsorbent for the removal of organophosphorus pesticides in Chinese cabbage and green onion samples.
