摘要

以小型环隙式离心萃取器为核心器件

设计了一套用于钚元素的环隙式离心萃取系统。该系统在2000 8000 r/min离心转速和1/3-1两相流比（o/a）范围内

水力学性能表现良好

无明显夹相;以0.1 mol/L TOPO/环己烷为萃取体系

0.01 mol/L草酸溶液为反萃体系

在短时间内完成6 mol/L HNO3溶液中Pu（IV）的萃取分离操作

其中两级萃取率大于90%

单级反萃率超过96%

显示出该系统萃取速度快、效率高的特点

可用于钚元素的快速提取。

Abstract

An extraction system with annular centrifugal extractors has been designed to separate plutonium.It worked well when centrifugal speed was ranged from 2000 to 8000 r/min and organic-aqueous flow ratio（o/a） ranged from 1/3 to 1

without obvious entraining phenomenon.Pu（IV） in 6 mol/L HNO3 solution was fast extracted and separated

using 0.1 mol/L TOPO/Cyclohexane as extraction solvent and 0.01 mol/L oxalic acid as back extraction solvent.The extraction ratio of two stages was larger than 90%

and the back ratio per stage was more than 96%.The extraction system shows fast operating speed and high extraction ratio

therefore it is suitable for fast extracting Pu.
