Am, Cm recovery from genuine HLLW by extraction chromatography

The extraction chromatography experiments for Am(III) and Cm(III) recovery from genuine HLLW were carried out in order to demonstrate modified 2 flow-sheets using CMPO/SiO 2 -P and HDEHP/SiO 2 -P adsorbents for obtaining DTPA-free MA(III) product solution. The first flow-sheet achieved about 90% MA(...

description The extraction chromatography experiments for Am(III) and Cm(III) recovery from genuine HLLW were carried out in order to demonstrate modified 2 flow-sheets using CMPO/SiO 2 -P and HDEHP/SiO 2 -P adsorbents for obtaining DTPA-free MA(III) product solution. The first flow-sheet achieved about 90% MA(III) recovery with more than 10 3 of decontamination factor for 155 Eu. However, further modification is necessary for separation of light lanthanides. Purification of MA(III) from both of heavy and light lanthanides was successfully done by the 2nd flow-sheet although recovery yields of MA(III) was almost the same with the current flow-sheet i.e. 70%. The recovery yield is expected to be improved by some optimizations in operation conditions such as column length, flow rate of the mobile phase and etc.
