目前,乏燃料后处理Purex流程的铀钚分离过程普遍采用四价铀作还原剂。在四价铀的各种制备方法中,电化学方法是一不需额外加入试剂、方便控制、易于实现连续化生产的方法。但传统的槽式电解装置,一般只有60%～70%的硝酸铀酰转化为四价铀。本文以钛涂钌铱网为阳极,钛网为阴极,建立了动态膜电 At present, uranium-plutonium-plutonium separation process for the spent fuel after-treatment Purex process generally uses tetravalent uranium as a reducing agent. Among various preparation methods for uranium tetravalent, the electrochemical method is a method that is easy to control and easy to realize continuous production without adding reagents. However, the conventional trough electrolyzer, generally only 60% to 70% of uranyl nitrate into uranium. In this paper, titanium coated ruthenium iridium mesh anode, titanium mesh as the cathode, the establishment of a dynamic membrane
