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

Sulfate radical AOPs (SR-AOP) were successfully utilized in degradation of antibiotics in water and wastewater treatment. The review discusses details on SR-AOPs mechanisms and applications for antibiotics degradation. The progress in this field was discussed, highlighting the most promising developments and remaining challenges. The applicability of SR-AOPs was summarized revealing the most susceptible and persistent to oxidation groups of pharmaceuticals. Highest effectiveness was reported for degradation of pharmaceuticals on ppb level. Systems revealed a scavenging effect in case of oxidant dose 0.7 mM of the PS and 2 mM of PMS. Future development demands simple persulfates activation systems for real matrix treatment.

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.
