V2O3 exhibited high catalytic activity toward PS decomposition for PCB28 degradation.
SO4limg="/entities/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">− and limg="/entities/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">OH radicals were produced from V2O3/PS system for PCB28 degradation.
TBA enhanced PCB28 degradation via reductive dechlorination with alcohol radicals.
Mechanisms for PS activation and PCB28 degradation were proposed.
