摘要

본 연구에서는 상용화된 양이온교환수지, 음이온교환수지, 혼합이온교환수지 각각 3종을 이용하여 Cs과 I 등의 방사성이온을 포함하고 있는 오염수 중 방사성 이온을 분리하는 연구를 하였다. 실험은 상온에서 회분식으로 진행하였으며, 이온교환수지의 양을 달리하여 각각의 이온교환수지에 대한 Cs와 I의 제염성능을 비교하였다. 이온크로마토그라피 기기로 농도분석을 한 결과, D사의 이온교환수지의 대체적으로 이온교환능력이 높은 결과 값을 가졌으며, 공통적으로 이온교환수지의 양이 적을 때, 이온교환수지 질량 대비 제염성능이 높은 것을 알 수 있었다. D사의 양이온교환수지의 질량이 적을 때, Cs 이온에 대한 이온교환용량은 0.199 meq/g, 음이온교환수지의 I 이온에 대한 이온교환용량은 0.344 meq/g의 결과 값을 확인할 수 있었으며, 혼합이온수지를 사용했을 때에는 I 이온에 대한 이온교환용량이 0.33 meq/g으로, D사의 이온교환수지가 다른 이온교환수지에 비해 특히 I에 대한 이온교환능력이 높은 것을 알 수 있었다. In this study, we used three kinds of commercially available cation, anion, and mixed-ion exchange resins to separate radioactive ions from a polluted water containing Cs, I, and other radioactive ions. The experiment was conducted at a room temperature with a batch method, and a comparative analysis on the decontamination ability of each resin for the removal of Cs and I was performed by using different quantities of resins. The concentration was analyzed using ion chromatography and the ion exchange resin product from company D showed an overall high ion exchange ability. However, for most of the experiments when the amount of ion exchange resin was decreased, the decontamination ability of the resins against mass increased. When the mass of company D's cation exchange resin was small, the ion exchange ability against Cs and I ions were measured as 0.199 and 0.344 meq/g, respectively. When the mixed ion exchange resin was used, the ion exchange ability against I ions was measured as 0.33 meq/g. All in all, company D's ion exchange resins exhibited a relatively higher ion exchange ability particularly against I ions than that of other companies' exchange ions.
