摘要

本實驗利用「雙－吡唑啉酮」Bi-pyrazolone（H_2LL），在甲苯溶液中萃取銦離子，In^(3+)。|M|與|M|利用原子吸光儀測定。反應在不同酸鹼值，H_2LL濃度等條件下進行，並與「吡唑啉酮」Pyrazolone（HL）之結果相比較。H_2LL-TOPO之協同作用亦加以研究。實驗結果顯示：萃取時生成錯合物In（HLL）（LL）；反應平衡常數，log K，之平均值為1.65±0.07。H_2LL之萃取能力比HL大（D^(H2LL)/D^(HL)≃31.5）。TOPO對H_2LL有正協同性質，得log K之平均為4.19±0.11。

並列摘要

In this study, In^(3+) in CIO^-_4 aqueous solution was extracted by Bi-pyrazolone (H_2LL) in toluene solution. The |M|,|M| were measured with AAS. The reaction was carried out under conditions of pH, |H_2LL| etc. Those results were compared with that of pyrazolone (HL). The synergic effect of H_2LL-TOPO was studied also. The results of this experiment show that a complex In (HLL) (LL) is formed. The average value of equilibrium constant, log K, is 1.65±0.07. The extraction efficiency of H_2LL is better than that of HL (D^(H2LL)/D^(HL)≃31.5). TOPO is a positive synergic agent, log K=4.19±0.11.
