Research Interests
Our laboratory investigates the remediation technology which uses the TiO2 photocatalysis for purification and treatment of water and air. 2-Chlorobiphenyl (2-CB) is used as the model compound. The studies involve the determination of the mechanism and kinetics of the photocatalysis and the effects of various factors on photocatalytic processes. The supported catalysts are also being investigated. Design and development of an energy-efficient photocatalytic module for improving indoor air quality is the next focus. The application of UV/TiO2 technology for the treatment of PCB vapor from soil extraction will also be studied.
We are also engaged in the development of instrumentation and methodology for the determination of PCBs and organochlorines in environmental and biological samples. The separation of coplanar PCBs and PCDD/Fs from conventional PCBs is particular our interest.
The fate constants (water solubility, octanol-water partition coefficient and Henry's Law constant) are experimentally determined for coplanar and semi-coplanar PCBs in our laboratory. Distribution of coplanar PCBs in the natural environment can often be described with physicochemical properties which are determined in the laboratory. To predict the fate and transport of coplanar PCBs, the methodology for laboratory measurement of these fate constants are developed.
