Carbon nanotubes supported cobalt nickel sulphide nanoparticles (nano-NiCo2S4@CNTs) were successfully prepared by a hydrothermal method as heterogeneous catalyst which can be used an activator of peroxymonosulphate (PMS) for the degradation chloroquine phosphate (CQP). Based on characterisation techniques, has excellent surface properties and structural stability. When different concentrations CQP treated with 0.2 g/L nano-NiCo2S4@CNTs 1.0 mM PMS, highest rate could reach 99.86% after 30 min. Under interference pH, common anions humic acid in water environment, reaction system still achieve high efficiency, showing anti-interference ability practical applicability. Furthermore, nano-NiCo2S4@CNTs/PMS system, according to identification results reactive oxygen species, free radical non-free pathway are responsible CQP, PMS mechanism activation was comprehensively proposed. Twelve intermediate products detected process, possible pathways This toxicity analysis demonstrates that formed during pose lower environmental risks compared original pollutant. In addition, using four cycles, removal efficiency remains above 80%, indicating reusability low metal ion leaching characteristics. Therefore, synthesised this research broad application prospects activating wastewater treatment.

In this study, magnetic (Fe)-loaded biochar was successfully prepared by a simple impregnation pyrolysis method. Meanwhile, its degradation capability and mechanism for typical antibiotic metronidazole (MNZ) were systematically investigated under different conditions. The characterization of the synthesized material showed that specific surface area, pore diameter, volume changed significantly. Also, functional groups metal element Fe introduced on biochar, leading to better activate peroxymonosulfate (PMS). experiments removal MNZ in Fe-BC/PMS system can reach up 95.3% 60 min optimal Free-radical capture there several active species •OH, SO4•−, •O2−, 1O2 present catalyst synergistically degrade MNZ, among which SO4•− played major role; it also found be easily recycled still effective after uses. Further, main pathways include nitrohydroxylation, hydroxyethyl group deletion, carboxylation amino demethylation, oxidation, carboxylation. It is obvious magnetic-loaded Fe-BC, generated from waste rape straw crops, shows high catalytic performance pollutant degradation, providing an insight into recycling potential biomass field removal.
