NOVELTY - Preparing heterogeneous fenton catalyst of cyclodextrin/reducing graphene modified ferroferric oxide involves adding 20 milligram graphene oxide, dispersing in 20 milliliter glycol and ultrasonic processing in ultrasonic cell crushing instrument for 30 minute for future use. The 0.4 gram of ferric trichloride hexahydrate, 1.13 gram sodium acetate, 0.3 gram polyethylene glycol and 20 milligram beta-CD are added to dispersion and mixture is magnetically stirred for 30 minutes for future use. The dispersion is transferred into 50 milliliter polytetrafluoroethylene reaction kettle and reacted for 8 hours at 200 degrees C. The reaction solution is cooled to room temperature, generated precipitate, then repeatedly wash for 3 times with de-ionized water and ethanol, after sample is vacuum dried at 50 degrees C for 12 hours and recycled to obtain sample, then grind sample for use. USE - Method for preparing heterogeneous fenton catalyst of cyclodextrin/reducing graphene modified ferroferric oxide. ADVANTAGE - The method enables to prepare heterogeneous fenton catalyst of cyclodextrin/reduce graphene modified ferroferric oxide that has excellent catalytic performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for using catalyst to obtain heterogeneous fenton catalyst of cyclodextrin/reducing graphene modified ferroferric oxide, which involves mineralizing and degrading bisphenol A rapidly by catalyst, using repeatedly for 5 times and maintaining removing efficiency at 80% or more.
