MA recovery experiments from genuine HLLW by extraction chromatography

Watanabe, So  ; Senzaki, Tatsuya; Shibata, Atsuhiro  ; Nomura, Kazunori  ; Koma, Yoshikazu  ; Nakajima, Yasuo  

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.
