2. Thèmes de recherche
- UV-based advanced oxidation (UV/H2O2, UV/persulfate) of wastewater effluent, degradation kinetics of micropollutants, identification of transformation products by high-resolution mass spectrometry,
- Formation potential of disinfection by-products (DBPs) during chlorination and chloramination of natural organic mattter and model compounds, identification of new DBPs,
- Inactivation of antibiotic resistant batceria and degradation of plasmid-based antibiotc resistance genes (ARG) during conventional disinfection and UV-based advanced oxidation processes, transformation of ARG to non-resistant receipent cells
3. Recherches en cours
My current research focuses on the UV and UV-based advanced oxidation of wastewater effluents. Non-target screening using high resolution mass spectrometry (Vion IMS QTof, Waters) is applied to comprehensively characterize micropollutants and their transformation products during oxidative treatment. Formation potential of disinfection by-products (e.g., trichloromethanes, haloacetonitriles, nitrosamines) is additionally monitored using GC-MS due to the presence of organic nitrogen and halide precursors in wastewater. Chemical characterization of wastewater effluent exposed to oxidative treatments will be combined with various toxicity tests (e.g., zebrafish larvae tests, in vivo cell tests).
These research activities are conducted within ANR WaterOmics research project : characterization of micropollutants and their transformation products in wastewater during UV-based advanced oxidation processes,
