Abstract
AbstractOrganic pollutants, including mycotoxins, organic dyes, and pesticide residues, are the most critical threats to the global environment. In particular, efficient adsorption based on synthetic nanomaterials is considered a versatile and green approach to control mycotoxins. This work systematically investigates the aflatoxin B1 (AFB1) removal capacity of MIL‐101(Fe), a typical type of metal‐organic framework (MOF) synthesized by solvothermal methods and possesses super‐high porosity and excellent dispersion in liquid. The experimental results demonstrate that as‐prepared MIL‐101(Fe) exhibits a much higher saturated loading capacity (30.58 mg g−1) toward AFB1 than other adsorbents described in the literature. Subsequently, the adsorption process is studied via isothermal and kinetic analyses. This work also evaluates the removal effect of MIL‐101(Fe) on organic dyes and pesticides compared to the other five MOFs; the results reveal that MIL‐101(Fe) possesses a diversity of pollutant adsorption. The molecular docking and interaction region indicator analysis is applied to reflect the interactions between AFB1 molecules and MIL‐101(Fe). This work will provide a simple and effective approach for AFB1 treatment and adsorption in wastewaters and offer new insights and perspectives to the practical applications of synthetic nanomaterials, MOFs in environmental management.
