Beschreibung
Zusammenfassung:	The present invention relates to: a method for reforming powdered activated carbon by using a polymer and forming a Prussian blue on the surface of powdered activated carbon; and an adsorbent material having cesium adsorption capacity through the same. When a powdered activated carbon cesium adsorption material according to the present invention is used, as many Prussian blues are fixed to the adsorption material, a high adsorption effect on cesium is exhibited. 본 발명은 분말 활성탄을 고분자로 개질하고, 분말 활성탄의 표면에 프러시안 블루를 형성하는 방법 및 이를 통한 세슘 흡착능을 가지는 흡착 소재에 관한 것이다.
