| Abstract;The extraction behavior of Ln(III) and Am(III) with N,N'-dimethyl-N,N'-diphenyl-malonamide (MA), -diglycolamide (DGA) and -3,6-dioxaoctanedioic diamide (DOODA) and the structural properties of their complexes were investigated. The distribution ratios of Ln(III) and Am(III) increase in the order MA<DOODA<DGA. The structural parameters were obtained by EXAFS. The carbonyl oxygen atoms in all the diamide complexes directly coordinate to Ln(III). In the DGA and DOODA complexes, the ether oxygen atoms also directly bind to Ln(III). (author abst.) |
