| چکیده | ||
| In this work, carrier-facilitated transport of Ag+ ion from an aqueous source phase (SP) containing Hg2+, Pb2+, Zn2+, Cr3+ and Co2+ through an against its concentration gradient from aqueous 5 ml (5.0 × 10−4 mol L−1) hydrochloric acid solution across a liquid membrane containing through an organic membrane phase (MP), 10 ml Bis-2,6-dihydroxymethyl-4-haloanisole (DABDAMA) (3.8 × 10−4 mol L−1) solution as a carrier into an aqueous receiving phase (RP), 5 ml Sodium thiocyanate (4.0 × 10−4 mol L−1) solution was the most efficient receiving phase agent among several aqueous reagents tested. Fluxes and selectivities for competitive metal cation transport have been determined in a variety of source solution pH and membrane solvent types. The mobile carrier in chloroform has been investigated. The obtained results showed that the carrier is selective for Ag+ ion. The effect of different experimental conditions that affect the transport efficiency were studied and optimized. In the optimum condition, the transport of an Ag+ ion across the liquid membrane is more than 92% after 2.5 h. The carrier, DABDAMA, selectively and efficiently could able to transport Ag+ ion in the presence of other associated metal ions in binary system. | ||
