枸橼酸镓-~(67)Ga的制备

PREPARATION OF ~(67)Ga-CITRATE

摘要: 采用自制的磷酸三丁酯 (TBP)萃淋树脂作交换柱 ,应用反相分配色层法研究了6 7Ga与靶材料中Zn ,Cu ,Ni等元素及活化产物6 5Zn ,56 Co ,57Co的分离 ,建立了一个简便、快速生产枸橼酸镓 6 7Ga的方法。所得6 7Ga的放射性核纯达 99 5% ,每 37MBq6 7Ga中其它金属离子总量不超过2 5μg

Abstract: TBP extractive eluting resin is prepared. The separation of 67 Ga from targets materials Zn,Cu,Ni and activated products such as 65 Zn and 56 Co et al is carried out with the use of reversed phase partition chromatography. Radionuclidic purity of 67 Ga reaches 99.5 %. Overall quantity of other metal ions is not above 2.5 μg in 37 MBq 67 Ga.
