Description

technical field [0001] The invention belongs to the technical field of aflatoxin adsorption materials, in particular to the application of magnetic graphene carbon nanomaterials in aflatoxin adsorption. Background technique [0002] The adsorbent is the key to the adsorption process and has a great influence on the removal efficiency of toxins. At present, the widely studied adsorbents mainly include activated carbon, silicate, kaolinite, bentonite and montmorillonite. Activated charcoal has been recognized for removing AFB from vegetable oils 1 effective adsorbent, but research shows that the loss of vegetable oil per kilogram of activated carbon will reach 4.4 kilograms. Small particle sorbents are valuable because of their large surface area and low nutrient loss. Graphene nanomaterials have attracted attention due to their small size, large specific surface area, nontoxicity, and biocompatibility. Due to its excellent adsorption properties, graphene can be used as an...
