Abstract
Treatment of spent scintillation cocktail generated by analysis of radioactivity is one of important tasks for management of nuclear laboratories. This study proposed a procedure consists of adsorption of radioactivity and solidification of residual liquid wastes, and fundamental performance of each step was experimentally tested. Batch-wise adsorption showed excellent adsorption performance of Ni onto silica-based adsorbent, and chelate reaction was suggested as the adsorption mechanism by EXAFS analysis. Alkaline activate material successfully solidified the liquid waste, and TG/DTA and XRD analyses revealed that the organic compounds exist inside the matrix. Only 1 % of the loaded organic compounds were leaked from the matrix by a leaching test, and most of the organic compounds should be stably kept inside the matrix.
