Disclosed is a novel adsorbent for use in aMo/Tc generator, which is a medical diagnostic radioisotope generator, and in aW/Re generator, which is a therapeutic radioisotope generator. The adsorbent composed of sulfated alumina or alumina-sulfated zirconia exhibits adsorption capacity superior to that of conventional adsorbents, and is stable and is thus loaded in a dry state in an adsorption column so that the radioisotopeMo orW can be adsorbed. Thus, it is possible to miniaturize the column, and such a miniaturized column is small, convenient to use, and highly efficient, and extracts a radioisotope satisfying the requirements for pharmaceuticals, and thus can be useful for radioisotope generators extractingTc orRe.

Adsorbents for radioisotopes, preparation method thereof, and radioisotope generators using the same

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 forY such as 95% extraction efficiency or more from ICiSr/Y by using a column packed with 0.4 g of the adsorbent with a high-purity ofY, it can be usefully to be employed in the fields requiringY.
