Disclosed herein is an ra-dioisotope adsorbent including a bifunc-tional organosilane compound, including an organosiloxane functional group and a phosphate group, bonded on the surface of silica which is a bone structure of the adsor-bent, and a method of preparing the ra-dioisotope adsorbent, and a strontium/yttri-um generator using the radioisotope adsor-bent. Since the radioisotope adsorbent has a high adsorption capacity for 90.UPSILON. such as 95% extraction efficiency or more from ICi 90Sr/90.UPSILON. by using a column packed with 0.4g of the adsorbent with a high-purity of 90Y it can be usefully to be employed in the fields requiring 90.UPSILON.
Linvention concerne un adsorbant de radioisotope comprenant un composé organosilane bifonctionnel, incluant un groupe fonctionnel organosiloxane et un groupe phosphate, lié sur la surface de la silice qui est une structure du squelette de ladsorbant, et un procédé de préparation de ladsorbant de radioisotope, et un générateur de strontium/yttrium utilisant ladsorbant de radioisotope. Étant donné que ladsorbant de radioisotope possède une capacité dadsorption élevée pour 90Y, telle quune efficacité dextraction de 95 % ou plus à partir de 90Sr/90Y dICi en utilisant une colonne remplie de 0,4 g dadsorbant avec une pureté élevée en 90Y, il peut être utile de lutiliser dans les domaines nécessitant 90Y.
