In this study, an alternative application of supported liquid membranes (SLMs) containing specific ion carriers dissolved in supra molecular solvent (SUPRA) to the selective and simultaneous separation of Ag⁺ and Pb²⁺ ions from a dilute source solution is introduced. A two-membrane three-compartment cell was used. Two micro-porous polypropylene supported membranes loaded with dibenzyl-diaza-18-crown-6 (DBzDA18C6) and dicyclohexyl-18-crown-6 (DC18C6) dissolved in supra molecular solvent (SUPRA) were used for selective transport of silver (I) and lead (II) ions, respectively. At first, vesicles of decanoic acid (SUPRA), as green solvent, were synthesized. Then, each of two mentioned crown ethers was easily dissolved into the SUPRA phase and used as the selective membrane phase for facile and simultaneous transport of lead and silver ions through the designed cell. The DBzDA18C6-loaded membrane was placed between the first and the second compartments (MP₁), whereas the DC18C6-loaded membrane was placed between the second and the third ones (MP₂) of the transport cell. Using this cell assembly, simultaneous separation and transport of Ag⁺ and Pb²⁺ ions are possible from a 1.854 × 10^–4 M picric acid source solution containing these two species and several other interfering ions into the two corresponding receiving compartments of the transport cell. The silver (I) and lead (II) ions quantitatively transport during 75 and 15 min of time into two individual receiving solutions, respectively. Sodium thiosulfate (0.6 M at pH 6.4) and sodium pyrophosphate (0.25 M at pH 7) were used as selective stripping agents for Ag⁺ and Pb²⁺ ions (RP₁ and RP₂), respectively.

在这项研究中，包含溶解在超分子溶剂 (SUPRA) 中的特定离子载体的支撑液膜 (SLM) 的替代应用，以选择性和同时分离 Ag ⁺和 Pb ²⁺引入来自稀释源溶液的离子。使用两膜三室细胞。用溶解在超分子溶剂（SUPRA）中的二苄基-二氮杂-18-冠-6（DBzDA18C6）和二环己基-18-冠-6（DC18C6）负载的两种微孔聚丙烯支撑膜用于银的选择性转运（I）和铅 (II) 离子。首先，合成了作为绿色溶剂的癸酸囊泡（SUPRA）。然后，提到的两种冠醚中的每一种都很容易溶解到 SUPRA 相中，并用作选择性膜相，以便铅和银离子通过设计的电池轻松和同时传输。加载 DBzDA18C6 的膜放置在第一和第二隔室之间（MP ₁），而DC18C6加载膜置于所述第二和第三那些（MP之间₂输送单元的）。使用此单元组件，可以将 Ag ⁺和 Pb ²⁺离子从 包含这两种物质和其他几种干扰离子的 1.854 × 10 ^–4 M 苦味酸源溶液中同时分离和传输到传输单元的两个相应接收隔室中. 银 (I) 和铅 (II) 离子分别在 75 和 15 分钟的时间内定量传输到两个单独的接收溶液中。硫代硫酸钠（pH 6.4 时为 0.6 M）和焦磷酸钠（pH 7 时为 0.25 M）用作 Ag ⁺和 Pb ²⁺离子 (RP₁和 RP ₂ )，分别。
