摘要：

Adsorptivity of metal ions onto silica-supported benzo-18-crown-6 (B18C6) and dibenzo-18-crown-6 (DB18C6) resins was investigated in nitric acid and hydrochloric acid media to evaluate the applicability of these resins for selective separation of nuclides from radioactive waste solutions. Both resins adsorbed Pd(II) and Ag(I) from HNO3, and Fe(III) and Ba(II) from HCl. It was also found that the B18C6 and DB18C6 resins adsorbed Sr(II) from HCl and Ca(II) from HNO3, respectively. This indicates that the two resins adsorb metal ions with smaller cationic diameters with different selectivity. This behavior is different from other impregnated adsorbents and extractants containing the 18-crown-6 moiety.
