| Abstract | AbstractSupported liquid membranes (SLM) using organic solvents are limited by their relative instability and high volatility. The use of supramolecular solvents (SUPRASs) as a liquid membrane phase could overcome these disadvantages due to their negligible vapor pressure and high viscosity. In the present study, a highly facile and selective transport of silver ions through a SLM using a SUPRAS composed of vesicles of decanoic acid was developed. The SLM used was a thin porous membrane impregnated with dibenzyl-diaza-18-crown-6 (DBzDA18C6), as a selective ion carrier, dissolved in the SUPRAS. Effective parameters including the concentration of picric acid, as a counter ion, in the source phase (SP), nature of solvent and amount and type of carrier in the membrane phase and nature and concentration of stripping agent in the receiving phase (RP), and nature and amount of stripping agent in the RP were investigated. In the presence of 8.85 × 10−5 M, picrate ion as a suitable bulky ion pairing agent in the S... |
