The transport behaviors of silver ion were observed from source solution into receiving solution through PIM regardless of ligand lipophilicity when acyclic polyether bearing diamine end-group was used as an organic carrier. Polymeric Inclusion Membrane (PIM) showed faster transport of silver ion than Supported Liquid Membrane (SLM) even though 10-fold diluted source concentration (PIM- 0.01 M, SLM- 0.10 M) was used. A maximum efficiency with respect to the permeability coefficient of silver ion was in the combination of 10 mM of acyclic polyether and 10 mM of silver ion utilized in PIM system. The PIM gave the best permeability coefficient (-7.00) comparing with for SLM system (-8.40), indicating that PIM gave 15 times better permeability for silver ion than the SLM system. In cellulose triacetate (CTA) membrane, organic carrier and solvent do not leak out into the agitated aqueous phases giving a long-term stability and good durability.
