  • Adsorbents for radioisotopes, preparation method thereof, and radioisotope generators using the same
    Patent number: 8758714
    Abstract: Disclosed is a novel adsorbent for use in a 99Mo/99mTc generator, which is a medical diagnostic radioisotope generator, and in a 188W/188Re 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 radioisotope 99Mo or 188W 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 extracting 99mTc or 188Re.
