Chemical and toxicological evaluation of an emerging pollutant (enrofloxacin) by catalytic wet air oxidation and ozonation in aqueous solution

► CWAO was applied for the first time to degrade high concentration of a widely used antibiotic. ► The comparison of CWAO and ozonation to test their efficiency to degrade pharmaceutical is unique. ► The degradation products were identified by LC-MS/MS, GC-MS and IC. ► The degradation efficiency of enrofloxacin was determined by COD, TOC, BOD5/COD and toxicity.
