Abstract
The present invention relates to a radionuclide adsorbent, which includes a hollow space (specifically, an area which is entirely empty or in which transition metal oxide particles are present); and a transition metal-ferrocyanide shell (specifically, a transition metal-ferrocyanide shell having a structure in which a plurality of two-dimensional nano flakes overlap or a transition metal-ferrocyanide shell having a structure in which a plurality of three-dimensional nano polyhedrons agglomerate) formed on the space surface, a preparation method thereof, and a method of removing a radionuclide using the same.
