As an emerging light source, ultraviolet emitting diodes (UV-LEDs) are adopted to overcome the shortcomings of conventional mercury lamp, such as pollution. The degradation chloramphenicol (CAP) using three UV-LED-based advanced oxidation processes (AOPs)—UV-LED/persulfate (UV-LED/PS), UV-LED/peroxymonosulfate (UV-LED/PMS) and UV-LED/chlorine—was investigated. Results indicate that CAP can be m...
