Extraction chromatography experiments with two promising flow-sheets on genuine high level liquid wastes were carried out for demonstrating the feasibility of the method. One flow-sheet consists of CMPO/SiO $_{2}$ -P and HDEHP/SiO $_{2}$ -P adsorbent columns, and the other consists of TODGA/ SiO $_{2}$ -P and isoHex-BTP/SiO $_{2}$ -P adsorbent columns. Although recovery yields of MA and decontamination factors of FPs obtained by those experiments were lower than the required values, the second flow-sheet is expected to achieve the required performance providing that some minor improvements on the flow-sheet or the adsorbents are applied.
