摘要:
在双驱动磁力搅拌釜内,探讨FeⅡ(EDTA)溶液吸收NO的传质反应动力学.实验结果表明:在pH值为6.0,温度为50℃的实验条件下,FeⅡ(EDTA)溶液吸收NO气体为快速拟一级反应,所得到二级反应速率常数k2=1.41×108L.(mol.s)-1.实验增强因子与吸收液浓度的平方根成正比,将其与膜模型计算得到的理论增强因子进行比较,两者最大误差小于6%.
Abstract:
The mass transfer and kinetics of the absorption of NO in aqueous FeⅡ(EDTA) solutions were studied in a double-stirred reactor.The results indicated that the chelation of NO to FeⅡ(EDTA) was the pseudo-first order reaction model.The forward second-order rate constant was determined from experimental results and found to be 1.41×108 L·(mol·s)(-1) at pH 6.0 and 50 ℃.The experimental enhancement factor was linear fit to the square root of the concentration of the absorption solution.Comparing the experimental value with the data calculated from film model,the maximum error was found to be less than 6%,which is permitted in the research of gas-liquid reaction.
