The recovery rate and DF of difficult-to-recover platinum group elements, Mo, Zr, etc., were investigated on a TEHDGA column for MA+Ln co-recovery. From the results of this study, it was confirmed that the difficult-to-recover elements were eluted well and DF was improved by optimizing the concentration of complexing agent and acid.
