摘　　要：简要介绍了从燃煤烟气中吸收NO废气的技术现状,自行设计了反应系统,对比了六氨合钴(Ⅱ)溶液吸收NO废气的优越性,分析了影响其工作效果的各操作参数。结果表明,在入料O2为5%、入料流量为500ml/min时,最佳的实验条件是:温度19℃,pH值10.5,六氨合钴(Ⅱ)溶液浓度为0.06 mol/L。The state-of-the-art of removal of NO from flue gas was briefly introduced,a reactive system was self-built;the priority of using hexamminecobalt（Ⅱ） solution was compared,and the effect of each operational parameter on removal performance was analyzed.The results show that the best NO removal efficiency was attained at a temperature of approximately 19 °C,pH value of around 10.5,and [Co（NH3）6]2＋concentration of 0.06 mol/L when inlet,O2=5% and the inlet flow rate =500 ml/min.
