FACILITATED TRANSPORT OF CARBON DIOXIDE: A REVIEW

Abstract
The effect of reversible chemical reaction upon the diffusion of carbon dioxide in thin liquid film membranes is reviewed. Particular emphasis is placed upon the hydration reaction of CO2 and catalysis thereof. Theoretical analysis is developed for equilibrium, near-equilibrium and near-diffusion regimes. The important effects of weak acid buffers, proteins and amines upon CO2 transport are also discussed, as well as the significance of diffusion potentials, particularly in the case of protein systems. Results of experimental investigations of facilitated CO2 transport are reviewed, as well as general aspects of CO2 transport in biological systems and absorbers.
