Accelerated mass transfer of palladium(II) through a selective solid-supported liquid membrane containing Cyanex 471

Transport of Gold Ion from a Hydrochloric Acid Solution across a Supported Liquid Membrane Containing Sulfide Podand

“…4 the enrichment of gold with the application of the above-mentioned membranes is compared. The ratio of both aqueous phases is 500 ml : 50 ml (curves 1-4) or 500 ml : 10 ml (curves 5,6). From the 50 ml receiving phase 1 ml aliquots were collected periodically, whereas separate runs were performed for 10 ml strip phases.…”

Iodide‐selective electrodes based on a mercury‐triisobutylphosphine sulfide complex

“…These studies led to the development of methods for the isolation of such metals from mixed-sulfide minerals and spent automotive catalysts [2,4]. The extraction of Hg'+ into an organic phase by formation of complexes with TIBPS (symbolized here as L) is governed by the following chemical equilibria 1131:…”

“…Triisobutylphosphine sulfide (TIBPS) has been used as a metal carrier in the separation and selective membrane transport of strategically important metals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. These studies led to the development of methods for the isolation of such metals from mixed-sulfide minerals and spent automotive catalysts [2,4].…”

Combinatorial synthesis of fluorescent trialkylphosphine sulfides as sensor materials for metal ions of environmental concern

“…7,8 Triisobutylphosphine has been used as a carrier in solvent extraction and solid supported liquid membranes. [9][10][11] It has been demonstrated that the reaction equilibrium for the coordination of ligands to form a monomeric complex, is similar to that occurring internally with polymers which contain the same binding ligand. 12 A polystyrene support was covalently bonded to the anthracene molecule which has been used as the fluorophore, and a phosphine sulfide group attached to anthracene as a recognizing receptor.…”
