“…Moreover, the target material, 96 Ru, has only 5.52 % natural abundance. The 3 He induced reaction on natural Mo target offers comparatively low production yield for 97 Ru. Moreover, numbers of Tc impurities like 93,94,95,96,99m Tc, via nat Mo( 3 He,pxn) reactions are introduced.…”

“…Therefore generation of nuclear and chemical data for the production of ruthenium radionuclides became important. Amongst all other ruthenium radioisotopes, 97 Ru became most important candidate in nuclear medicine (T 1/2 = 2.83 d; decay mode: EC (100 %); two intense low energy c-lines: 216 keV, 324 keV). Presently 97 Ru are produced with the help of both neutron and light charged particle induced reactions, like 96 Ru(n, c), 103 Rh (p, 5n 2p), nat Ag(p, xn yp), 99 Tc(p, 3n), nat Mo( 3 He, xn), nat Mo(a, xn), 95 Mo(a, 2n), etc.…”

“…Moreover, numbers of Tc impurities like 93,94,95,96,99m Tc, via nat Mo( 3 He,pxn) reactions are introduced. The a-particle induced reactions on natural molybdenum target introduce long-lived [61] produced 97 Ru by bombarding 67.5 MeV proton on natural rhodium target. The yield of 97 Ru was very high, 1.36 mCi/lAh at EOB, but contaminated with numerous radionuclides.…”

The yield of 97 Ru was very high, 1.36 mCi/lAh at EOB, but contaminated with numerous radionuclides. Therefore, it became relevant to examine thoroughly the heavy ion induced production route of 97 Ru.…”

Iron oxide–coated fibrous sorbents for arsenic removal

et al. 2008

View full text Add to dashboard Cite

Iron oxide‐coated sand has been demonstrated to be an effective adsorbent material for the removal of arsenic and other metals and metalloids from drinking water and wastewater. In this study, fibrous materials were evaluated for their ability to offer a high specific surface area alternative to sand as the substrate for the iron oxide coating. Four types of fibrous materials, polypropylene, polyester, fiberglass, and cellulose, were evaluated for their ability to retain iron coatings and to remove arsenate. Sand was also evaluated to provide a basis for comparison with previous research. In isotherm experiments, all four fibrous materials showed higher arsenate adsorption densities than iron oxide‐coated sand. Arsenate adsorption densities were highest for iron oxide‐coated fiberglass and cellulose, suggesting that these fibrous materials may offer advantages over iron oxide‐coated sand.
