【 摘 要 】

References(7)Cited-By(10)The characteristics of the liquid membrane with tri-w-octylamine were elucidated. This liquid membrane spontaneously concentrates metals without controlling the concentrations of the agent which provides the driving force to the uphill transport of metals. The rate of iron permeation through the liquid membrane is dependent on the diffusional resistances in two aqueous phases, the diffusional resistance in the membrane phase, and the interfacial resistances. When the acid concentration in the aqueous raffinate phase is large, the interfacial resistances are negligibly small, and the diffusional resistance in the membrane phase is also negligibly small at high amine concentration in the membrane phase. In this case, the permeation rate is controlled only by the diffusional resistance in the raffinate phase.
