Research interests:
Our research interests are the fate and transformation of organic pollutants in the environment.Atmospheric Chemistry: For the past decades， our research focused on the fate and transformation of volatile organic compounds (VOCs). Using theoretical calculations， experimental measurements， and atmospheric modelling， we have explored the fate of a variety of VOCs in the atmosphere， including the aromatic compounds， terpines， and furans from biomass processes， etc. We introduced the important intramolecular H-migration pathway in oxidation of aromatic compounds and dimethyl sulfide， virtually reforming their oxidation mechanism.Emerging Pollutants: Emerging organic pollutants have strong impact in aqueous ecosystems. We are interested in the fate of emerging organic pollutants in envirnmental waters. We have studied the photochemical degradation mechanism of a few ECs， including a few ionic liquids， a few drugs and pesticides， etc， by experimentally measuring their quantum yields of UV photolysis， the rate coefficients for their reactions with OH radical， sulfate anion radical， triplet CDOM*， and singlet oxygen， etc. Modelling studies were carried out based on these kinetic paraters to estimate their persistence and degradation mechanism.
