Abstract: THE EFFECT OF SnO2·xH2O ON ADSORPTION CHARACTERISTICS FOR 68Ge68Ga GENERATORLiu Zhenghao Jia Congli(Department of Chemistry, Beijing Normal University,100875)Abstract The hydrate SnO2·xH2O that used as absorbent of 68Ge/68Ga generator is prepared. Some parameters on the generator are investigated with the use of imitation experiment. It is found that the hydrate SnO2·xH2O have better selective absorbability for Ge. The elution efficiency for Ga is near 88% with 2.0 mL 01 mol/L HCl solution.Key words 68Ge68Ga generator absorption elution SnO2·xH2O
