摘要： Trivalent actinides can be separated from trivalent lanthanides in aqueous solutions at H.sup.+ concentrations of 2 mol/l to 0.001 mol/liter by extraction with bis(aryl)dithiophosphinic acid and a synergist such as TBP, TOPO and TBPO in an organic solvent. A high separation efficiency results. The method is applicable to high-level liquid waste from reactors and nuclear-material processing plants.

摘要： The invention relates to a method for separating trivalent americium from trivalent curium. According to the inventive method, an aqueous solution containing at least said cations is contacted, at an acid concentration of 0.01 mol/L to 1 mol/L, with an organic solvent containing a bis(aryl)dithiophosphinic acid of general formula (4), wherein R1=phenyl- or naphthyl, R2=phenyl- or naphthyl, with methyl-, ethyl-, propyl-, isopropyl-, cyano-, nitro-, halogenyl-(Cl−, F−, Br−, J−) substituted radicals of R1 and R2, R1 and R2 being optionally substituted by at least one component from the group comprising methyl-, ethyl-, propyl-, isopropyl-, cyano-, nitro-, halogenyl-(Cl−, F−, Br−, J−), and with a synergist of general formula (5), wherein X and/or Y and/or Z=RO (=alkoxy) or R (=alkyl), R being optionally branched and/or unbranched. The separation factor for americium (III) and curium (III) has an order of magnitude of 10.
