Facilitated transport of molecular oxygen in membranes (poly(dimethyl siloxane), poly(butyl methacrylate), and poly(methyl methacrylate)) containing cobalt(II) or iron(II) alpha , alpha prime , alpha double prime , alpha prime double prime -meso-tetrakis (o-pivalamidophenyl)porphyrin as a fixed carrier of oxygen is studied by the combination of oxygen permeability in the membranes and oxygen-binding ability to the metalloporphyrin. The facilitation of oxygen transport is remarkable for the lower upstream pressure, which corresponds to a dual-mode transport model. The facilitation is more enhanced in the polymer matrix with the lower oxygen solubility (according to Henry's law). Although the oxygen-binding affinity of the iron porphyrin is larger than that of the cobalt porphyrin, the facilitation is lower because of its smaller oxygen-binding kinetic constant.
