Abstract

The facilitated transport of oxygen in a liquid membrane containing [meso-α,α,α,α-tetrakis(o-pivalamidophenyl) porphyrinatocobalt(II)]-laurylimidazole (CoP) as an oxygen carrier leads to high permeability and permselectivity of oxygen against nitrogen. The oxygen permeation was properly analyzed by a dual-mode model and using the oxygen-binding constants spectroscopically determined, to give permeation parameters of the membrane such as the diffusion coefficient (DCoP) of the CoP mobile carrier and the physical diffusion coefficient of oxygen. DCoP was in accordance with that electrochemically determined. The facilitated permeation was represented by the product of the CoP concentration and DCoP in the membrane solution. DCoP decreased with solution viscosity and increased with the measured temperature. High oxygen permeability (10-7 cm3(STP) cm cm-2 s-1 cmHg-1) was observed, e.g. for the membrane of the 31 wt % CoP methylanisole solution at 10 °C, where the facilitation factor and the oxygen/nitrogen permselectivity were over 20 and 40, respectively.
