Description

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 organicaqueous flow ratio was ranged from 1/3 to l, 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, as well as 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 suitable for fast separating Pu solution. (authors)
