title: [Experimental research for simultaneous removal of SO2 and NOx by aqueous oxidation of O3].
abstract: The removal of SO2 and NOx by aqueous oxidation of O3 was studied by self-designed bubbling reactor. The results show that NO can be oxidized efficiently by O3 in liquid phase, while the existence of SO2 has a negative impact on the removal of NO and pH value has a little impact. The NO removal efficiency is 89.6% at [O3]/[NO] = 1.1. When the rang of pH value is in 3-11, NO removal efficiency can be achieved over 80%. At 20-65 degrees C, NO removal efficiency has no change. Combining with wet scrubbing tower, SO2 removal efficiency is nearly 100% and NO2 removal efficiency is 84.2% at [O3]/[NO] = 1.1. SO2 and NOx can be removed effectively by aqueous oxidation of O3 simultaneously.
