| 英文摘要 | Lithium extraction from ammoniacal solution with thenoyltrifluoroacetone (HTTA) and neutral ligand was studied in various organic solvents. The remarkable enhancement of lithium extraction was observed by the addition of neutral organophosphorus compounds and the experiments showed that trioctylphosphine oxide(TOPO) was preferable for lithium extraction. The synergistic effect of thenoyltrifluoroacetone and trioctylphosphine was studied in detail and the results indicated that the strongest enhancement coefficient was 1205 when molar ratio of two extractants was 1:1. The extracted lithium complex was found to be Li center dot TTA center dot TOPO by slope method and the results of thermodynamic study indicated that the extraction process was spontaneous exothermic process and the degree of disorder increased after extraction. In addition, stripping and regeneration condition of organic phase were investigated in detail. It was demonstrated that the synergistic extraction system containing HTTA and TOPO could effectively separate lithium and other alkali metal ions and was feasible for lithium extraction from ammoniacal solution.
