Applicability of tetra2-ehylhexyl diglycolamide (TEHDGA) impregnated adsorbent for minor actinide (MA) recovery from high level liquid waste (HLLW) in extraction chromatography technology was investigated through batch-wise adsorption and column separation experiments. Distribution ratio of representative fission product elements were obtained by the batch-wise experiments, and TEHDGA adsorbent was shown to be preferable to TODGA adsorbent for decontamination of several species. All Ln(III) supplied into the TEHDGA adsorbent packed column was properly eluted from the column, and the applicability of the adsorbent was successfully showed by this study.

通过分批吸附和柱分离实验研究了四 2-乙基己基二甘醇酰胺 (TEHDGA) 浸渍吸附剂在萃取色谱技术中从高放废液 (HLLW) 中回收微量锕系元素 (MA) 的适用性。通过分批实验获得了代表性裂变产物元素的分布比，并且表明 TEHDGA 吸附剂比 TODGA 吸附剂更适合几种物种的净化。所有供应到 TEHDGA 吸附剂填充柱的 Ln(III) 都从柱子中被正确洗脱，本研究成功地展示了该吸附剂的适用性。
