本工作的重点是应用聚合物包合膜（PIM）与三辛基甲基铵硫代水杨酸盐，[A336][TS]（TOMATS），一种含硫醇的任务特定的离子液体用于运输钯（II）离子从水溶液中。0.3 M硫脲在0.1 M盐酸中被认为是最有效的反萃取相在运输Pd（II）从膜相含有TOMATS。还从含有Pt（IV）、Fe（III）、Ni（II）和Mn（II）的盐酸溶液中分离Pd（II）离子。Pd（II）离子优选在这些金属离子的存在下运输。分离系数的大小顺序为：SPd/Pt<SPd/Fe<SPd/Ni<SPd/Mn。[A336][TS]是一种优良的盐酸溶液中Pd（II）的离子载体。结果还表明，PIM的传输效率是可重复的，它可以是有用的，从废催化剂浸出液中回收Pd（II）的简单和高效的方法的发展。
This work focuses on the application of polymer inclusion membrane (PIM) with tricaprylmethylammonium thiosalicylate, [A336][TS] (TOMATS), a thiol-containing task-specific ionic liquid for the transport of Pd(II) ions from aqueous solutions. 0.3 M thiourea in 0.1 M hydrochloric acid was found the most effective stripping phase in the transport of Pd(II) from membrane phase containing TOMATS. Separation of Pd(II) ions was also carried out from hydrochloric acid solution containing Pt(IV), Fe(III), Ni(II), and Mn(II). Pd(II) ions were preferably transported in the presence of these metal ions. The separation coefficients followed the order:SPd/Pt<SPd/Fe<SPd/Ni<SPd/Mn. [A336][TS] proved to be an excellent ion carrier for Pd(II) from hydrochloric acid solution. The results also showed that transport efficiency of the PIM was reproducible and it can be useful for the development of the simple and highly effective method of Pd(II) recovery from leach liquor of spent catalysts.
