Reactions of F element ions in aqueous solution with sulfur donor atom ligands
Description
This study shows that the dialkyldithiophosphate complex UO2(DTP)+ exists in aqueous solution. Complexes richer in ligand are observed in organic phases in contact with aqueous solutions. In the case of pentavalent ions the compound NpO2(DTP), xH2O precipitates if the alkyl radical is butyl, with ethyl or methyl radical no precipitation occurs. An effect produced by the length of the ligand organic chain is observed as in the case of the uranium VI complex

Dans le cas des ions pentavalents on peut precipiter le compose NpO2(DTP), xH2O avec le radical butyl. Lorsque le radical est ethyl ou methyl aucun solide n'est observe. Comme dans le cas de la formation du second complexe de l'uranium (VI), un effet du a la longueur des chaines organiques du ligand est observeFiles
