| Abstract: | Synergistic extraction of samarium with TTA(HA) and TPPO or TOPO (B) mixtures were investigated. The extracted complex was proved to have the general formula SmA3 · 2B. A graphical determination for the formation constants of these complexes gave the values 3.9 × 1013 and 8.2 × 1010 for SmA3 · 2TOPO and SmA3 · 2TPPO in benzene, respectively. |
