Degradation of Antibiotics via UV-Activated Peroxodisulfate or Peroxymonosulfate: A Review
CATALYSTS(2022)
摘要
The ultraviolet (UV)/H2O2, UV/O-3, UV/peroxodisulfate (PDS) and UV/peroxymonosulfate (PMS) methods are called UV-based advanced oxidation processes. In the UV/H2O2 and UV/O-3 processes, the free radicals generated are hydroxyl radicals (center dot OH), while in the UV/PDS and UV/PMS processes, sulfate radicals (SO4 center dot-) predominate, accompanied by center dot OH. SO4 center dot- are considered to be more advantageous than center dot OH in degrading organic substances, so the researches on activation of PDS and PMS have become a hot spot in recent years. Especially the utilization of UV-activated PDS and PMS in removing antibiotics in water has received much attention. Some influencing factors and mechanisms are constantly investigated and discussed in the UV/PDS and UV/PMS systems toward antibiotics degradation. However, a systematic review about UV/PDS and UV/PMS in eliminating antibiotics is lacking up to now. Therefore, this review is intended to present the properties of UV sources, antibiotics, and PDS (PMS), to discuss the application of UV/PDS (PMS) in degrading antibiotics from the aspects of effect, influencing factors and mechanism, and to analyze and propose future research directions.
