摘要
在改进的传质池中研究了 3种表面活性剂对硝酸反萃体系传质的影响。实验表明 ,在不加界面激励时 ,表面活性剂的存在大大降低硝酸反萃的传质系数 ;加界面激励时 ,阴、阳离子表面活性剂会增加硝酸反萃的传质系数 ,非离子表面活性剂则减小传质系数。
The effect of three kinds of surfactants on mass transfer in the system of HNO_3 strip-extraction was studied in the modified extraction cell. Experiments showed that without interfacial prompting the mass transfer coefficient was reduced greatly in the process of HNO_3 strip-extraction by adding three kinds of surfactants. Meanwhile, with interfacial prompting the mass transfer coefficient was increased in the process of HNO_3 stripping by adding the anion and the cation surfactant, and was deceased by adding the non-ion surfactant.
