摘要:
为实现NO的低温氧化,在液相体系中,以温度23~65 ℃考察耦合微波的芬顿试剂/活性炭催化氧化NO的效果.采用对照实验论证连续稳定施加微波对芬顿试剂的强化作用,包括热效应和敏化效应;研究微波功率、初始pH值、AC添加量、Fe2+初始浓度、H2O2初始浓度等因素对NO脱除效果的影响,最终得出最佳反应工况.结果表明:微波结合活性炭能够显著提高NO脱除效率;反应最佳工况为微波功率400 W,pH=3,AC添加量为4 g,Fe2+初始浓度为5 mmol/L,H2O2初始浓度为0.3 mol/L,此时NO脱除效率达到46.3%.

Abstract:
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%.
