Abstract
The extraction of europium with benzene solutions of tributyl phosphate (TBP), benzoic acid (BA), and acetylacetone (AA) from nitrate solutions has been studied in the presence of the following polyfunctional organic compounds: acrylamide (AAm), phenanthroline (Phen), Diacetam-5, and Tinuvin-622. Europium distribution data in combination with luminescence spectroscopy of extracts are used to discuss europium complexing with the specified ligands. A feasibility of manufacturing Eu2O3 and EuPO4 films on quartz through the pyrolysis of saturated extracts is demonstrated.
