摘要

•A method of vapor oxidation combined with dual-area absorption was developed.•The SO2 removal efficiency reached 99.3%.•The NO conversion efficiency was up to 96.3%.•The key oxidizing species were determined as HO by ESR.•The main byproducts were determined as (NH4)2SO3, NH4NO2 and (NH4)2SO4 by IC.
