摘要

本文章進行鎳-63純化分離方法評估，樣品經適當前處理後，由Ni樹脂層析純化、分離，再以閃爍計數儀量測，並可搭配自動化固相萃取儀，可有效縮短純化分離時程，且化學回收率可達80%以上。

An analytical method for the determination of Ni-63 in nuclear waste was investigated. Ni-63 in nuclear waste samples was properly digested with acid, purified and separated from other interfering radionuclides with highly selective Ni Spec. resin. The activity concentration of Ni-63 was then measured by a liquid scintillation counter. Alternatively, the automated solid phase extraction system can be used to purify Ni-63 and the separation time can be effectively reduced. The chemical yield of the separation procedure can achieve more than 80%.
