1 Electrochemical oxidation Research topics Evaluation of microbicidal efficacy using conventional disinfection process (e.g. H2O2, Cl2, O3) and advanced oxidation processes. (AOPs; e.g. Fe(II)/H2O2, UV/H2O2, O3.H2O2)Investigation and optimization of microbicidal efficacy for influencing factors in various water samples such as freshwater, seawater, and wastewater Development of efficient homogeneous catalysts/heterogeneous catalysts/photocatalysts for enhanced inactivation of microorganisms (e.g. bacteria, virus, and fungi) Elucidation of microbicidal mechanism (e.g. membrane, protein, gene damages) behind various redox reactions
