본 총설논문에서는 과거 방사능누출 사고사례를 제시하고 그에 따른 위험성을 논하였다. 또한 방사성 폐액 내의 방사성 이온들을 제거하기 위한 방법을 대별하고 실증사례들을 열거하였다. 여러 가지 방법을 복합적으로 사용한 실험결과 및 특허가 많이 있지만, 국내기술이 해외기술에 비해 미미한 실정이다. 후에 일어날 수도 있는 사고에 대비해서라도 국내 기술력의 발전과 경쟁력은 꼭 필요하다. 본 논문을 통해 방사성 이온 제거에 대한 현재 기술상황을 고찰하고 발전가능성에 대해 알아보고자 하였다.
This review article indicated accident examples in the past and discussed dangerousness according to these examples. In addition, the ways to remove radioactive ions in radioactive waste, they were divided broadly and enumerated experimental case. These were many results of the experiment and patent...

이온교환법은 무엇인가? | 이온교환법은 이온교환수지를 사용하여 원수 중의 이온성분을 제거하는 방법으로 국내뿐만 아니라 세계적으로 많이 적용되고 있는 방법이다[16]. Fig. | |
CDI 기술은 무엇에 기반하여 이온을 제거하는 기술인가? | CDI (capacitive deionization) 기술은 전기이중층에 기반하여 이온을 제거하는 기술이다. 전극에 전위를 인가하였을 때 전극 계면에 형성되는 전기이중층에서의 흡착 및 탈착과정을 통해 이온성물질을 제거한다. | |
오염된 방사성 폐수를 처리하기 위해 어떤 방법들이 사용되는가? | 이러한 심각하게 이미 오염된 방사성 폐수를 처리하기 위해 많은 연구가 진행되고 있고, 추후 다시 발생할 수 있는 재난현상에 대비하여 위기에 대응하기 위해서도 심층적인 연구가 진행되고 있다. 사용하고 있는 처리 방법으로는 크게 이온교환, 막 분리, 흡착, CDI, MCDI 등의 방법을 복합적으로 사용하고 있다. 본 문헌은 선택적 방사성 핵종 제거 기술의 동향에 대해 고찰하고자 한다. |
