Selective Separation of Silver(I) Ion Through a Bulk Liquid Membrane Containing 1,1'-(1,3-Phenylene)bis(3-allylthiourea) as Carrier

Selective Transport of Silver(I) Cation Across a Bulk Liquid Membrane Containing Bis-β-enamino Ester as Ion Carrier

“…Nezhadali et al 31 applied a bulk liquid membrane for selective separation of Ag + cation using 1,1'-(1,3-phenylene) bis(3-allylthiourea) as a carrier and their results, showed that the transport efficiency of this metal cation for the five replicate measurements after 4 h, was 92.3 ± 5.3%. The results obtained in our experiments, show a better efficiency and precision for selective transport of Ag + ion through bulk liquid membrane using bis-β-enamino ester (BBEE) ligand.…”

The (CF3C(O)NH)(C6H5CH2NH)2P(O) phosphoric triamide as a novel carrier with excellent efficiency for Cu(ii) in a liquid membrane transport system

“…25 1 H-, 13 C-, 19 F-and 31 P-NMR spectra were recorded on a Bruker Avance DRX 400 spectrometer. Chemical shis were determined relative to TMS for 1 H and 13 C and relative to CFCl 3 for 19 F, and 85% H 3 PO 4 for 31 P as the external standards. Infrared (IR) spectrum was recorded on a Buck 500 scientic spectrometer using a KBr disc.…”

“…26,27 The synthesis and melting point of (F 3 CC(O)NH)(C 6 H 5 CH 2 -NH) 2 P(O) (PTC) was also reported 27 and the procedure described here for PTC is similar to the literature method with a few modications (in solvent and the reaction temperature). Moreover, we further study this compound with IR, NMR ( 31 P, 1 H, 13…”

“…[1][2][3][4] Towards this aim, various separation techniques are well-known, such as plasma atomic emission spectrometry, 5,6 liquid chromatography, [7][8][9] cloud point extraction, 10 and ion transport methods using a bulk liquid membrane (BLM) system that has attracted attention in recent years. [11][12][13][14][15] The use of a BLM containing specic metal ion carriers offers an alternative to the solvent extraction processes for the selective separation and concentration of metal ions from aqueous solutions.…”

Application of Polymer Inclusion Membranes Doped with Alkylimidazole to Separation of Silver and Zinc Ions from Model Solutions and after Battery Leaching

“…The solutions obtained as a result of leaching are subjected to separation processes, which may include separation with liquid membranes [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Various carriers are used in membrane processes, e.g., thiourea derivatives [ 26 , 27 ], phosphoric acid derivatives [ 28 , 29 ], calixpyrroles [ 30 , 31 ], crown ethers [ 32 , 33 , 34 , 35 , 36 ] or calixarene [ 37 ]. Currently, polymer membranes are the most popular for membrane processes, which are increasingly used in the separation of various metal ions [ 38 , 39 , 40 ].…”
