This paper begins with a brief overview of relefvant research within the contexts of industrial-scale gas separations (i.e., absorber/stripper systems) as well as membrane-based systems, the latter of which have at times been used to model transport in blood and other physiological media.
It then examines the fundamental physico-chemical phenomena and parameters - e.g., relative time scales of diffusion and reaction, ionic diffusion potential effects, reaction-based coupling of the transport of two acid gases -as well as the effects of weak acid buffers, amines, amino acids and proteins, upon transport rates and selectivity.
It concludes with a discussion of promising areas for future research.
