- 論文の詳細を見る
Heat-generating nuclides Cs and Sr were separated from simulated high-level liquid wastes <BR>(HLLW) by successive adsorption on columns of ferrierites (F) and zeolite A. Adsorbed Cs and Sr were efficiently eluted with NH<SUB>4</SUB>NO<SUB>3</SUB> and EDTA solutions, respectively, yielding the recovery over 96%. A simulated waste solution containing 29 components was denitrated with a formic acid up to pH 7.92. The amounts of nuclides adsorbed from this denitrated solution were experimentally estimated to be 0.33 mmol Cs/g•F and 0.19 mmol Sr/g•A, respectively.
