IRN-150 혼상수지의 이온 흡착특성 및 폐수지로부터 탈착용액을 이용한 14C 핵종의 제거 특성
Ion Adsorption Characteristics of IRN-150 Mixed Resin and Removal Behavior of 14C Radionuclide from Spent Resin by Stripping Solutions
Abstract
Spent ion-exchanged resin generated from various purification systems in CANDU reactor was contaminated with high activity of radionuclide. This paper describes the results of fundamental study to develop the applicable technology for the treatment of this spent resin. Based on the adsorption capacity of inactive ion and other anions on IRN-150 mixed resin, the removal characteristics of ion adsorbed on to IRN-150 by various stripping solutions were evaluated. Maximum adsorption amount of the ion onto IRN-150 raw resin was about 11 mg-C/g-resin which agrees with the theoretical adsorption amount of this resin. Adsorption affinity of various anions such as was analyzed in single and multi-component systems. From the results of removal characteristics of the ion adsorbed on IRN-150 by various stripping solutions, stripping solution is more effective than solutions for the complete removal of radionuclide from the IRN-150 spent resin.
