摘要
以磷酸二异辛酯(DMHPA)为流动载体,对U(Ⅵ)的乳状液膜传质动力学进行了研究。测定了外相硝酸浓度、膜相载体浓度、温度等因素对传质速率的影响。实验结果表明,该体系在硝酸介质中对U(Ⅵ)的一次回收率达96%以上。并求得初始传质速率方程,计算了表观传质反应热。
The transfer kinetics of uranium () through an emulsion liquid membrane with Di(1methylheptyl) phosphoric acid (DMHPA) as a mobile carrier has been investigated. The experimental results show that more than 96% of the initial U() is recovered. The influence of various factors,such as the concentration of carrier and nitric acid,temperature,on the rate of transfer is studied. The transfer rate equation is experimentally obtained and the superficial transfer energy is calculated.
