摘　　要：为制备适用于68Ge-68Ga发生器的吸附剂,用热HNO3氧化金属锡制备SnO2,对SnO2吸附剂的制备工艺及其性能进行了研究。制备得到以SnO2作为吸附剂的68Ge-68Ga发生器,并对其吸附行为与淋洗效率进行了研究。结果表明,600℃高温焙烧获得的SnO2适于用作68Ge-68Ga发生器的吸附剂,其对68Ge有较好的选择性吸附,用8 mL 1 mol/L HCl淋洗,68Ga的淋洗效率为60%~80%,68Ge的漏穿率大部分为10-3%量级。For preparing the absorbent of 68Ge-68Ga generator,SnO2 was prepared with metal tin and hot HNO3.The process and characters of SnO2 were studied.The features of adsorption and elution of 68Ge-68Ga generator with SnO2as the absorbent were also studied.The results indicate that SnO2 after heated at 600 ℃ is suitable as absorbent for 68Ge-68Ga generator,and it has good selective adsorption to 68Ge.The 68Ga yield is 60%-80% with 8 mL of 1 mol/L HCl as the eluent,and the 68Ge breakthrough is most a magnitude of 10-3%.
