IBIL and EXAFS analyses were carried out on an adsorbent impregnating CMPO and HDEHP extractants for the extraction chromatography technology in order to evaluate chemical structure of complex formed in the adsorbent. EXAFS analysis suggested that contributions of CMPO and HDEHP for Eu(III) extraction must be not only individual ones but also cooperative. IBIL spectra obtained for the adsorbent were attributed to complexes of Eu(III) with organic compounds, and the profile was sensitive to coordination structure of the organic compounds. Those analytical technologies were shown to be effective to investigate chemical environment of cation charged in organic compounds. Two dimensional imaging using specific luminescence was also tried on the adsorbent, and required performance for the system to evaluate distribution of the complexes inside the particle was clarified.
