Times Cited Count:3 Percentile:73.63(Chemistry, Multidisciplinary)We investigated the distribution mechanism of Eu(III) in a single polymer-coated silica particle including nitrilotriacetamide (NTA) extractants known as HONTA and TOD2EHNTA. The present study provides a valuable approach for the evaluation and enhancement of the functionality of "single extractant-impregnated polymer-coated silica particle".

We developed a hybrid MA(III) recovery process combining MA(III)+Ln(III) co-recovery flowsheet by solvent extraction with TBP and MA(III)/Ln(III) separation flowsheet by simulated moving bed chromatography using HONTA impregnated adsorbents with large particle size porous silica support.

Neutron resonance absorption imaging was adapted to observe the Eu band adsorbed in the CMPO/SiO-P column for minor actinide recovery by extraction chromatography. Several wet columns were prepared by either light water or heavy water and compared with the dry column to evaluate the neutron transmission. The neutron transmission spectra showed that 45% was transmitted through the dry column while 20% and 40% were transmitted through the wet columns of light water and heavy water, respectively. The results indicated that heavy water is more applicable than light water to observe the Eu adsorption band in the CMPO/SiO-P column.

Extraction chromatography has been employed to separate minor actinides (MAs) from spent nuclear fuel for the purpose of reducing environmental impact. In our strategy, the polymer-coated SiO particle with an extractant is packed in a column and utilized for group separation and/or isolation of the specific element (Am and Cm, for example) from high level liquid waste. The safety use of chromatography was assessed by irradiation to the adsorbent with He beam and ray to simulate the high-level nuclear waste. In this study, we focused on a recently developed extractant TODGA and its degradation behavior on top of the SiO-P adsorbent was investigated by a similar experimental manner.
