The Behavior of Uranium in the Extraction with Benzyldodecylamine
Nippon kagaku zassi, 1961 アミン類は選択性の面で他の溶媒とくらべてすぐれているため,ウランの抽出に広く使用されている。このうちペンジル基をもつ第ニアミン類は高い抽出力をもち着目されているが,こめ種のアミン類による抽出の基礎が明らかでない。したがってベンジルドデシルアミンを使ってウランの抽出挙動および抽出機構を調べた。硫酸ナトリウム0.1～1.0mol/l,酸性度0.1～1.0Nの広い範囲でウランは1:1硫酸錯塩の形で実質上完全に有機層に抽出され,有機層内では抽出された硫酸ウラニル1分子についてベンジルドデシルアミンの4個が配位する。

Uranium Extraction From Laboratory-Synthesized, Uranium-Doped Hydrous Ferric Oxides
Environmental Science & Technology, 2009 The extractability of uranium (U) from synthetic uranium-hydrous ferric oxide (HFO) coprecipitates has been shown to decrease as a function of mineral ripening, consistent with the hypothesis that the ripening process will decrease uranium lability. To evaluate this process, three HFO suspensions were coprecipitated with uranyl (UO2(2+)) and maintained

Uranium Extraction from Syrian Phosphate: A case Study [PDF]
International Journal of Economic and Environment Geology, 2010 Uranium and trace elements were studied in few hundred samples from phosphatic formations in Syria. Uranium and trace elements were enriched in phosphorites facies compared to carbonate and siliceous facies.
