Traditional Fenton reaction can hardly achieve the simultaneous desulfurization (de-SO 2) and denitrification (de-NO x) for the cement kiln exhaust gas, due to the low production of free radicals as the limited Fe 2+ /Fe 3+ cycle. Herein, an enhanced Fenton oxidation process was developed to remove SO 2 and NO x efficiently, through improved Fe …
