Beschreibung
Zusammenfassung:	Disclosed herein is an radioisotope adsorbent including a bifunctional organosilane compound, including an organosiloxane functional group and a phosphate group, bonded on the surface of silica which is a bone structure of the adsorbent, and a method of preparing the radioisotope adsorbent, and a strontium/yttrium generator using the radioisotope adsorbent. Since the radioisotope adsorbent has a high adsorption capacity for 90Y such as 95% extraction efficiency or more from ICi 90Sr/90Y by using a column packed with 0.4 g of the adsorbent with a high-purity of 90Y, it can be usefully to be employed in the fields requiring 90Y.
