Single and multi-antibiotics removal via peroxymonosulfate activation using molybdenum disulfide (MoS): Central composite design and degradation pathway.

The efficacy of molybdenum disulfide (MoS) for the degradation of metronidazole (MET), tetracycline (TET), and ciprofloxacin (CIP) in single and multicomponent systems through peroxymonosulfate (PMS) activation was investigated. Several characterization techniques, such as SEM, XRD, XPS, and EPR were performed to understand the removal mechanism of the three antibiotics in PMS/MoS system. In single component system with an initial antibiotic concentration of 10 mg L, >95% removal of MET, TET, and CIP were observed within 60 min (PMS = 100 mg L; MoS = 0.
