Zusammenfassung:	The present invention relates to a radionuclide absorbent, a method for preparing the same, and a method for removing radionuclide by using the same. The radionuclide absorbent of the present invention is capable of removing radioactive cesium ion (Cs^+) and/or strontium ion (Sr^2+) more selectively than conventional zeolites even in the presence of various competing ions (for example, Na^+, K^+, Mg^2+, Ca^2+) in underground water or seawater. Also, the radionuclide absorbent of the present invention can be prepared by a simple method of heat-treating a mixture of sulfur and zeolite, and sulfur in zeolite can be uniformly dispersed by the method. 본 발명은 방사성 핵종 흡착제, 이의 제조방법 및 이를 이용한 방사성 핵종의 제거 방법에 관한 것이다. 본 발명의 방사성 핵종 흡착제는 기존 제올라이트에 비해 지하수나 해수의 다양한 경쟁 이온들 (예를 들어 Na, K, Mg, Ca) 존재 하에서도 훨씬 선택적으로 방사성 세슘 이온(Cs) 및/또는 스트론튬 (Sr)을 제거할 수 있다. 또한 본 발명의 방사성 핵종 흡착제는 황(sulfur)과 제올라이트의 혼합물을 열처리하는 간단한 방법으로 제조가 가능하며, 상기 방법에 따라 제올라이트 내에 황을 균일하게 분산시킬 수 있다.
