Synthetic methods of uranium and neptunium compounds from solutions

Saeki, Masakatsu

In this review, synthetic methods of uranium and neptunium compounds mainly from solutions and their natures are summarized. For uranium, 3 compounds of trivalent, 4 compounds of tetravalent and 23 compounds of hexavalent are described in slight details. For neptunium, synthetic methods of stock solutions for pentavalent and hexavalent neptunium, 4 items (6 compounds) of trivalent, 8 items (19 compounds) of tetravalent, 28 items (29 compounds) of pentavalent, 10 items (14 compounds) of hexavalent and 5 items (9 compounds) of heptavalent are described in slight details. Furthermore, on compounds which can not be described in details, the names are listed with literatures. The materials used here have been collected during the research activities on Moessbauer spectroscopic studies of uranium and neptunium compounds, then, the reviews on Moessbauer spectroscopic studies of actinoid compounds are also listed.
