从废旧⁶³Ni放射源中回收⁶³Ni原料技术

摘要: 为了从废旧⁶³Ni放射源中回收⁶³Ni原料，对物理方法、化学方法和电化学方法优缺点进行比较后确定了电化学方法为较优工艺，本研究优化得到电化学法退镀液的组成、浓度以及工艺参数，该方法回收的⁶³Ni原料比活度较高，可以重新用于⁶³Ni源的生产。

Abstract: The processes technology of recycling nickel-63 from spend nickel-63 radioactive source were studied. The electrochemical method was choosed as the better process. It obtained the composition and concentration of stripping solution, the process parameters of electrochemical method. Nickel-63 raw material recovered by this method could be used for production of nickel-63 source again for its high specific activity.
