At present, the disposal of refractory organics attracted more and more interest and highlighted for its difficulty of degradation ability.This study focus on the degradation of HCB, quinoline, indole by microwave assisted photocatalyic. In the study, effect of degradation in the different technologies combined with UV, TiO2, MW is also discussed.The results are as follows:(1) The sequence of the degradation rate of HCB in different systems is UV/P25 < UV < MW < MW/UV |
