Fluorometric Microdetermination of Uranium. II. Extraction of Uranium [PDF]
Bulletin of the Chemical Society of Japan, 1950 Abstract A minute amount of uranium suitable for the fluorometric method of determination is effectively precipitated from the solution together with hydrous ferric oxide as co-precipitator. The efficiency of co-precipitation seems to be nearly perfect for the purpose, and the adsorption and the digestion effect were observed in ...

Metal-Half-Salen Chemistry for One-Pot Mineralization on Hydrophobic Polymer Membranes. [PDF]
Adv Sci (Weinh)Here we report a versatile one‐pot synthetic strategy for organic–inorganic composite membranes, which leverages a metal half‐Salen system to precisely govern the competing kinetics of coordination and hydrolysis. In contrast to conventional two‐step metal‐phenol chemistries, our integrated approach substantially simplifies the fabrication process ...
