▎ 摘　　要

NOVELTY - Method for synchronously detecting six aflatoxins based on graphene nanomaterial involves contacting the sample solution with the graphene coating, so that the graphene coating adsorbs aflatoxin in the sample solution and analyzing the aflatoxin adsorbed on graphene coating to release and detect aflatoxin. USE - The method or stirring rod is useful for synchronously detecting six aflatoxins. ADVANTAGE - The method utilizes a weak pi - pi interaction formed between graphene nanomaterial-rich large pi bonds and aflatoxin, which also has an aromatic ring large pi bond structure and adopts graphene coating which has good chemical inertness and thermal stability and does not release the coating itself into the aflatoxin during the analysis process, hence improves accuracy of aflatoxin detection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for stirring rod based on graphene nanomaterials, where the surface of the stirring rod is coated with a graphene coating.
