The Behavior of Uranium in the Extraction with Benzyldodecylamine

open access: yesNippon 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。

A Universally Applicable Strategy for Construction of Anti‐Biofouling Adsorbents for Enhanced Uranium Recovery from Seawater

open access: yesAdvanced Science, 2019
The ocean reserves 4.5 billion tons of uranium and amounts to a nearly inexhaustible uranium supply. Biofouling in the ocean is one of the most severe factors that hazard uranium extraction and even cause the failure of uranium extraction.
