Electrochemically activated peroxymonosulfate for the abatement of chloramphenicol in water: performance and mechanism

A highly dispersed magnetic polymetallic catalyst to activate peroxymonosulfate for the degradation of organic pollutants in wastewater

“…SO 4 ˙ − can be effectively generated by activating peroxymonosulfate (PMS). A variety of methods including heating, 15 ultraviolet (UV) photolysis, 16 ultrasound, 17 microwave irradiation, 18 electrolysis 19 and transition metal catalysis 20 have been reported to activate PMS. Among these activation methods, transition metal catalysis has been proven to be most attractive and economic using heterogeneous PMS catalysts, which does not require energy supply (such as high temperature, ultrasound and electricity) and only yields a slight secondary pollution.…”
