| 摘 要： | A new combined reactor with Hg/Ar electrodeless ultraviolet(EDUV)activated by DBD for 3,4-dichlorodiphenyl ether abatement is presented.The effect of specific input energy and feeding gas component on 3,4-dichlorodiphenyl ether removal efficiency has been explored.Compared with a single DBD system,this new combined process performed a significant promotion on 3,4-dichlorodiphenyl ether abatement.Experiment results verified that active oxygen clearly contributed to the synergistic activity of DBD-EDUV system.Results of emission spectra showed that UV radiation of 253.7 nm could be detected in the DBD-EDUV system.Further,the products of DBD-EDUV process were analyzed via gas chromatographymass spectrometer(GC-MS)to reveal involved decomposition mechanism.

| Abstract: | A new combined reactor with Hg/Ar electrodeless ultraviolet(EDUV) activated by DBD for 3,4-dichlorodiphenyl ether abatement is presented. The effect of specific input energy and feeding gas component on 3,4-dichlorodiphenyl ether removal efficiency has been explored.Compared with a single DBD system, this new combined process performed a significant promotion on 3,4-dichlorodiphenyl ether abatement. Experiment results verified that active oxygen clearly contributed to the synergistic activity of DBD-EDUV system. Results of emission spectra showed that UV radiation of 253.7 nm could be detected in the DBD-EDUV system. Further, the products of DBD-EDUV process were analyzed via gas chromatographymass spectrometer(GC-MS) to reveal involved decomposition mechanism. |
