PURPOSE:To easily and speedily separate, purify, and recover a relatively large amount of actinoids consisting of >=2 components by using the chromatography which can separate high-concentration actinoids exceeding two components by elements and valencies. CONSTITUTION:This CPC(centrifugal counter flow distribution chromatography) device has a fixed phase charged in a distribution cell 1 which can be rotated by a rotor 2. After a sample solution of a fission product in used nuclear fuel is admitted to the cell, separation is performed by chromatographic expansion by using a moving phase. The separation state can be known through a detector such as a absorbance monitor for the visible range and the concentration of each component of the separated eluate can be confirmed quantitatively by a high frequency induced coupling plasma light emission spectrochemical analyzer. Thus, a relatively large amount of actinoids consisting of >=3 components can be separated mutually and the separation is performed relatively speedily. This CPC device is easy in the replacement of the fixed phase, its cleaning, decontamination, etc., are easily, and the device which is relatively small in size can be constituted.
