▎ 摘  要

NOVELTY - A filter cloth comprises a reduced graphene oxide/polyvinyl formal fiber filter cloth composite material having regular structural morphology. The filter cloth is prepared by carrying out hydrothermal reduction reaction on graphene oxide and food-grade polyvinyl formal fiber filter cloth. USE - Filter cloth is useful for adsorption and removal of aflatoxin in edible vegetable oil, preferably peanut oil, corn oil and peanut blend oil (all claimed). ADVANTAGE - The filter cloth has excellent adsorption effect, and effectively reduces the pollution level of aflatoxin in edible vegetable oil. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) the method for preparing the filter cloth; and (2) the use of the filter cloth for removing aflatoxin in edible vegetable oil.
