钨和铼的色层分离研究
Investigation on chromatographic separation of tungsten and rhenium
【摘要】 以(187)W、(188)W- (188)Re为示踪剂.对W和Re在阴离子交换色层柱和酸性Al2O3色层柱上的吸附和解吸行为进进了系统研究,给出了W和Re的放射化学分离程序.实验结果表明,无论是阴离子交换色层柱还是酸性氧化铝生层柱都可使钨、铼达到满意的分离.推荐的分离程序可用于无载体(186)Re的制备.
【Abstract】 The adsorption and desorption behaviors of W and Re on anion exchange column and acidic alumina column have been studied. Radiochemical procedures are presented for the separation of W and Re. The experimental results show that a satisfactory separation between W and Re can be achieved. The radiochemical procedures will be useful to separate radiotherapeutical nuclide 186Re from W target which is irradiated with a high intensity proton beam.
