“…The conventional methods for treating residual drugs in water mainly include physical method, biological method and advanced oxidation methods Zhou et al 2020;Yang et al2021). Among various techniques, advanced oxidation processes (AOPs) with the advantages of high efficiency, fast and no secondary pollution has attracted more attention, such as photocatalytic degradation method (Hsiao et al 2014), persulfate oxidation method (Li et al 2023), bimetallic composite material method (Abdelkader et al 2011) and electrochemical reduction method (Khenifi et al 2012).…”

A novel CQDs-doped carbon nitride nanosheets composite (CNS/CQDs) for visible light-induced activation of peroxymonosulfate (PMS) for meloxicam (Mel) and tetracycline (TC) degradation was studied. The photocatalytic degradation of Mel and TC were remarkably promoted by CNS/CQDs under the simultaneous action of PMS and visible light irradiation. Mel photodegradation of 99.60% was achieved over 30 min with 20 mg CNS/CQDs and 20 mg PMS at pH11. And TC photodegradation of 95.97% was achieved over 45 min with 20 mg CNS/CQDs and 20 mg PMS at nature pH. The TOC mineralization rates of Mel and TC were 75.49% and 52.00%, respectively. The enhanced photodegradation of organic pollutants could be ascribed to be the efficient activation of PMS and the separation of photogenerated electrons and holes of CNS/CQDs. Capture experiments and EPR tests showed that in the CNS/CQDs+PMS+vis system, the effective active substances for Mel were mainly •O2 -, •SO4 -and h + , while the main active substances for TC were •O2 -, h + , and •SO4 -. This study provides valid residual drugs degradation under the dual conditions of visible light catalytic oxidation and persulfate oxidation, which will be a novel perspective for advanced oxidation technology to effectively remove organic pollutants from water.
