Abstract

|
|
The preferential transport phenomena of neutral cation-anion moieties in neutral macrocycle-facilitated emulsion liquid membrane were described in this study. Emulsion membrane systems consisting of (1) aqueous source phase containing 0.001M M(NO3)2 (M = Mn2+, CO2+, Ni2+, Cu2+, Zn2+, Sr2+, Cd2+, Pb2+) (2) a toluene membrane containing 0.02M ligand (DBN3O2, DB18C6) and the surfactant span 80 (sorbitan mono oleate) (3% v/v) and (3) aqueous receiving phase containing Na2S2O3 or NaNO3 were studied with respect to the disappearence of metal ions from the source phase as a function of time. Cation transport rates for various two component equimolar mixture of metal ions were determinded. Cd2+ was transported higher rates than the other M2+ in the mixture solution.
