主　　题：CoFe_(2)O_(4)/eggshell Peroxymonosulfate Florfenicol PVDF membrane 

摘      要：Eggshell-loaded CoFe_(2)O_(4) catalyst was synthesized via a convenient hydrothermal method during our work,then the surface morphology and elemental composition of the composites were systematically *** of CoFe_(2)O_(4)/eggshell-activated peroxymonosulfate(PMS)system was evaluated by selecting florfenicol(FF)as the model pollutant,and effects of operating parameters and water matrices on the FF removal efficiency in this system were *** addition,main radicals involved in FF degradation were identified by EPR tests and radical quenching experiments,and possible mechanism was *** reduction of toxicity during FF degradation was confirmed,and in combination with HP-LC tests,it was found that dehalogenation and defluorination were effectively carried out during FF *** addition,the prepared CoFe_(2)O_(4)polyvinylidene fluoride(PVDF)membrane effectively improved the stability of the material and reduced the precipitation of metals.
