| description | (1) Background: Safety problems associated with aflatoxin B<sub>1</sub> (AFB<sub>1</sub>) contamination have always been a major threat to human health. Removing AFB<sub>1</sub> through adsorption is considered an attractive remediation technique. (2) Methods: To produce an adsorbent with a high AFB<sub>1</sub> adsorption efficiency, a magnetic reduced graphene oxide composite (Fe<sub>3</sub>O<sub>4</sub>@rGO) was synthesized using one-step hydrothermal fabrication. Then, the adsorbent was characterized using a series of techniques, such as SEM, TEM, XRD, FT-IR, VSM, and nitrogen adsorption–desorption analysis. Finally, the effects of this nanocomposite on the nutritional components of treated foods, such as vegetable oil and peanut milk, were also examined. (3) Results: The optimal synthesis conditions for Fe<sub>3</sub>O<sub>4</sub>@rGO were determined to be 200 °C for 6 h. The synthesis temperature significantly affected the adsorption properties of the prepared material due to its effect on the layered structure of graphene and the loading of Fe<sub>3</sub>O<sub>4</sub> nanoparticles. The results of various characterizations illustrated that the surface of Fe<sub>3</sub>O<sub>4</sub>@rGO had a two-dimensional layered nanostructure with many folds and that Fe<sub>3</sub>O<sub>4</sub> nanoparticles were distributed uniformly on the surface of the composite material. Moreover, the results of isotherm, kinetic, and thermodynamic analyses indicated that the adsorption of AFB<sub>1</sub> by Fe<sub>3</sub>O<sub>4</sub>@rGO conformed to the Langmuir model, with a maximum adsorption capacity of 82.64 mg·g<sup>−1</sup>; the rapid and efficient adsorption of AFB<sub>1</sub> occurred mainly through chemical adsorption via a spontaneous endothermic process. When applied to treat vegetable oil and peanut milk, the prepared material minimized the loss of nutrients and thus preserved food quality. (4) Conclusions: The above findings reveal a promising adsorbent, Fe<sub>3</sub>O<sub>4</sub>@rGO, with favorable properties for AFB<sub>1</sub> adsorption and potential for food safety applications. |
