Gewinnung von Uran aus Lösungen

For the recovery of uranium from a solution in which the uranium has a valency (VI), a solution is formed containing ammonium (NH4), fluoride (F) and sodium hydrosulfite (Na2S2O4). This forms a precipitate (NaNH4UF6), a previously unreported compound. It can be dissolved in an aqueous solution of al...

Zusammenfassung:	For the recovery of uranium from a solution in which the uranium has a valency (VI), a solution is formed containing ammonium (NH4), fluoride (F) and sodium hydrosulfite (Na2S2O4). This forms a precipitate (NaNH4UF6), a previously unreported compound. It can be dissolved in an aqueous solution of aluminum nitrate nonahydrate, Al(NO3)3.9H2O. This produces uranyl nitrate hexahydrate, which can be extracted in solutions conventionally used for that purpose.
