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)3]2+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。
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.
