In this study the performance of catalytic ceramic membranes in activating peroxymonosulfate (PMS) for the degradation of emerging organic contaminants (EOCs) was investigated. The catalytic ceramic membrane (MnCM) integrated with Mn2O3 nanoparticles was fabricated by a solid-state sintering method. Phys. and chem. properties of MnCM were characterized by SEM/EDX, XRD, BET, AFM and XPS. The MnCM/PMS system has shown excellent decontamination efficiencies (81-97% removal) for different EOCs. Acetaminophen (APAP) has been efficiently degraded by MnCM/PMS in different real water matrixes and harsh water conditions. Based on results of quenching experiments and ESR (EPR) analyses, non-radical pathway with singlet oxygen (1O2) was the dominant ROS for the degradation of EOCs. The membrane pores in active layer acted as micro-reactors for the interaction among active sites, PMS, and EOCs. The MnCM/PMS system showed outstanding catalytic stability with high mineralization (TOC removal of ∼ 65%) and negligible leaching of the manganese (1.3-1.5μg/L) in permeate. Hydroxylation and C-N bond cleavage were found to be the main degradation pathways of APAP by MnCM/PMS system. The MnCM prepared in this study with excellent performance could be a way forward for applications at large-scale or full-scale water systems suffering from heavy loads or trace amount of refractory organic compounds In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Synthetic Route of C13H9Cl3N2O).
1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Synthetic Route of C13H9Cl3N2O
