Extraction Rate and Temperature Dependency of Distribution Ratio of 4f and 5f Series Element in the Various Phosphorus Compounds

국문 초록 (Abstract)

4f 및 5f 系列 元素의 溶媒抽出에 있어서 分配速度를 測定해 본 結果 4f 系列의 前半部와 後半部 間에 明白한 差異를 볼 수 있었다. 三價의 Am 및 Cm은 4f 系列의 前半部와 類似함을 알았다. 또한 分配率과 抽出溫度와의 關係를 檢討해 본 結果 抽出系에 따라 獨特한 增加 또는 減少傾向이 나타났으며 또한 Chelate 抽出系에 있어서는 原子番號 存在性이 있음을 알았다

The distribution rate of 4f and 5f series elements in chelate and ion association extraction system was studied. Clear difference between lighter and heavier part of 4f series are observed. Trivalent Am and Cm were appeared to be grouped into the lighter part of 4f series. And also the variation of distribution ratio according to the varied temperature was studied. The variation modes of distribution ratio are different according to the extraction system. Atomic number dependence in the chelate extraction system was observed.
