Abstract
The stability constants of the Sm(NO3)2+ complex were determined at three temperatures, using the solvent extraction method. It was found that:K 01 =63.6 at 17°C, 30.3 at 35°C, 20.1 at 50°C. This corresponds with the formation of a Sm(H2O)(NO3)2+ complex at 17°C and a Sm(H2O)2(NO3)2+ complex at 50°C.
Zusammenfassung
Die Stabilitätskonstanten von Sm(NO3)2+ Komplexen wurden mittels der Lösungsmittelextraktionsmethode bei drei Temperaturen bestimmt. Dabei ergab sichK 01 =63.6 bei 17°C, 30.3 bei 35°C und 20.1 bei 50°C. Das entspricht der Bildung eines Sm(H2O)(NO3)2+ Komplexes bei 17°C und eines Sm(H2O)2(NO3)2+ Komplexes bei 50°C.
