We focused on the extraction chromatography technique using HONTA impregnated adsorbent for MA (III)/Ln (III) separation from high-level radioactive liquid waste. In this study, we had the column test for evaluating the adsorption performance with the improved carrier.

Basic research for construction of MA (III)-Ln (III) co-recovery process by solvent extraction at high TBP concentration

no journal, ,

We investigated the effects of nitric acid, TBP and salting out reagent concentrations on the rare earth element (Ln (III)) extraction using TBP, which is inexpensive and has selective extractability. It was suggested that Ln (III) can be extracted by controlling the nitric acid and nitrate ion concentrations.

Two types of adsorbents were, respectively, prepared by impregnating nitrilotriacetamides (NTAamides) of HONTA and TOD2EHNTA in silica beads, and their adsorption properties for fission products (FPs), trivalent lanthanides (Ln(III)), and trivalent minor actinides (MA(III)) were clarified by single-stage batch experiments. Based on the results of the batch experiments, column experiments using HONTA adsorbents were performed by setting the nitric acid concentration and the flow rate of the eluents as parameters, and adsorption and elution behaviors of FPs, Ln(III) and MA(III) were evaluated.
