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。

Review of aluminum solubility behavior in the Hanford 200 South West Area tanks targeted for retrieval

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The behavior of aluminum‐bearing phases in tank wastes from the southwest quadrant of the Hanford Site's 200 West Area primarily determines solids accumulation, retrieval performance, and downstream processability. This review synthesizes historical tank characterization data, laboratory dissolution studies, and process‐relevant observations ...

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

Advanced 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.

Modelling of Uranium Extraction in Sulphuric Medium [PDF]

, 2012
A cationic extractant, 2-ethyl hexylphosphonic acid (PC88A), has been studied to recover uranium from conventional ore by solvent extraction. On the basis of experimental studies, extraction equilibria for uranium in sulphuric medium with PC88A were ...

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...
