| Due to the structural similarities between PCDD and PCDF congeners, we studied exposure to UV light of wavelength greater than 305nm on PCDD/F congener transformation. Temperature effects on PCDD/Fs are commonly study, however photolytic transformation is not well studied. We carried an investigated with a variety of PCDD/F congeners in a soil matrix exposed to UV with wavelength greater than 305nm at temperatures less than 30ºC. We observed dechlorination and an overall increase in furan concentrations. As an extension to this research, the effects of TiO2 as a possible catalyst for the photolytic congener transformation was also investigated. |
