To realize the NO oxidation at low temperature

the NO catalytic oxidation efficiency through Fenton reagent/AC coupled with microwave in the liquid system and within 23~65 ℃ temperature range was researched

in which the AC acts as wave absorption heating-spots based on its developed pores. At first

the invigorating effect of microwave on Fenton reagent was proved using compared experiment in detail

including thermal effect and sensitization effect. Then the effect of the microwave power

the initial pH value

the AC dose

the Fe2+ initial concentration and the H2O2 initial concentration on the NO removal efficiency was studied thoroughly

the optimal reaction parameters were reached at last. The results indicated that the AC combined with microwave could enhance the NO removal efficiency substantially. The optimal reaction parameters was that the microwave power was 400 W

the pH value was 3

the AC dose was 4 g

the Fe2+ initial concentration was 5 mmol/L and the H2O2 initial concentration was 0.3 mol/L. The NO removal efficiency under the optimal reaction conditions was up to 46.3%.
