Aflatoxin contamination in edible vegetable oils is an important public health issue. How to remove the aflatoxins in edible vegetable oil efficiently, quickly and safely is a scientific problem in the field of food safety. To remove the aflatoxins in the edible vegetable oils efficiently and safely, this project intends to adopt physical adsorption method. Firstly, a series of magnetic mesoporous graphene will be synthesized as the adsorbents for aflatoxins, which can high-selectively adsorb aflatoxins in the edible vegetable oils. Then the adsorption properties of the graphene-based materials were investigated. The adsorption mechanism was revealed by theoretical analysis of the material characterization data and the adsorption mode. In conclusion, the research of this project will provide the new methods for detoxifying of aflatoxins in edible vegetable oils. Meanwhile, this project can also provide the theoretical basis for the mechanism of the adsorption process of small molecules on mesoporous graphene.
