    Kinetics of NO Absorption in Aqueous Co(en)32+ Solution

    • 摘要: 采用双驱动搅拌反应器研究了乙二胺合钴溶液吸收NO的反应动力学。实验表明:Co(en)32 络合NO的反应对NO表现为1.8级反应,NO的吸收速率随气相中氧含量的增加而增加,在一定的pH范围内,NO的吸收速率随溶液pH的增大而增加。建立了乙二胺合钴溶液吸收NO的反应动力学方程。

       

      Abstract: The kinetics of the absorption of NO in aqueous Co(en)_3~(2 ) solution was studied in a stirred reactor.Factors influencing the NO absorption rate,such as pH,oxygen concentration and(Co(en)_3~(2 )) concentration were investigated.The reaction between NO and Co(en)_3~(2 ) is found to be (1.8) order with respect to the NO concentration.The experimental results indicate that NO absorption rate increases with increasing pH and oxygen concentration.A rate equation for NO absorption in aqueous(Co(en)_3~(2 )) solution under the influences of mass transfer is established.
