NOVELTY - A graphene charcoal filter material comprises shell activated carbon grains, and contains 1% charcoal graphene oxide in the bottom of the gap. USE - Graphene charcoal filter material used for detecting antibiotics in drinking water (claimed). ADVANTAGE - The filter material effectively removes antibiotics in drinking water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) the preparation method of graphene charcoal filter material, which involves weighing grain activated carbon column, adding graphene oxide dispersion liquid, drying, dispersing graphene oxide and water in a mass ratio of 250:1, stirring for 15-60 minutes, ultrasonically treating for 15-30 minutes, and repeatedly drying twice; and (2) the application of graphene charcoal filter material in detecting antibiotics in water.
