Activated persulfate and peroxymonosulfate based advanced oxidation processes (AOPs) for antibiotics degradation-A review

Zhila Honarmandrad et al.

Summary: Sulfate radical advanced oxidation processes (SR-AOP) have been successfully utilized for the degradation of antibiotics in water and wastewater treatment. This review discusses the mechanisms and applications of SR-AOPs in antibiotics degradation. The progress in this field, including the most promising developments and remaining challenges, is highlighted. The most susceptible and persistent oxidation groups of pharmaceuticals are summarized, and the highest effectiveness is reported for degradation of pharmaceuticals at ppb level. A scavenging effect is observed when the oxidant dose is 0.7 mM for the persulfate (PS) and 2 mM for the peroxymonosulfate (PMS). Future development requires simple persulfate activation systems for real matrix treatment.
