摘要
本文采用两相滴定法研究HTTA-TPhPO对五种三价稀土离子(Pr、Nd、Sm、Gd、Tm)的协同萃取机理.在15、20、25℃三个温度下,测定了各萃合物的分子组成及稳定常数,进而得出协萃反应的热力学函数.并与类似的协萃体系作了比较.
synerglstic extraction mechanism of flve RE(Ⅲ) lons with HTTA-TPhPO has been studled by using the two-phase titration method.Comppsitions and stability constants of synergistic complexes were determined at 15℃,20℃,25℃ respectively.The thermodynamical functions of extractive reac- tion were obtained,Which were compared with similar synerglstic systems.
