Report Abstract:

Advanced oxidation processes are important approaches for water purification and have been widely applied in drinking water disinfection, advanced wastewater treatment, and water reuse. However, these processes involve various short-lived reactive species (such as radicals), whose generation and transformation pathways are highly complex, making mechanistic elucidation and process regulation challenging. Transient spectroscopic techniques enable the capture of transient intermediates and the characterization of rapid reaction kinetics. Nevertheless, their further application in environmental systems is limited by spectral interference and signal attenuation caused by complex matrices in real water environments. This presentation will introduce the speaker's research progress in the development and optimization of transient spectroscopic techniques, as well as their applications in investigating the reaction kinetics of emerging contaminant transformation and the mechanisms underlying the formation of harmful disinfection byproducts. The potential future applications of these techniques in environmental science and engineering will also be discussed.
