Advanced oxidationprocesses for the treatment of organicpollutants in wastewater suffer from difficulties in mineralization, potential risks of dissolved residues, and high oxidant consumption. In this study, radical-initiated polymerization is dominated in an UV/peroxydisulfate (PDS) process to eliminate organicpollutant of pharmaceutical metoprolol (MTP). Compared with an ideal degradation-based
