Reactivity of Natural Organic Matter in Advanced Oxidation Processes and Implications for Catalytic Ceramic Membrane Application
MetadataShow full item record
The reactivity (kinetics, reactive sites) of SO4•– with natural organic matter (NOM) showing different structural character was compared with that of •OH using ultrahigh resolution MS (FT-ICR MS). The interfacial interaction between NOM and Mn-oxide nanoparticles used as catalyst for radical production was studied using TR-DLS and AFM. Based on the findings, the antifouling property and self-cleaning performance of SO4•–-based catalytic ceramic membrane (i.e, Mn-oxide nanoparticles coating activated by peroxomonosulfate) was comprehensively investigated.
