The rates of diffusion through two fluorinated groups and two non-fluorinated groups of laboratory prepared membranes were compared with each other and with commercially available cellulose membranes. The membranes.were evaluated, in particular, for possible use with the artificial kidney. Diffusion experiments were conducted with sodium chloride, urea and uric acid. Experimental results were compared to diffusion coefficients calculated in the literature for cellulose membranes. The results show that the rates of diffusion of all of the solutes tested for the laboratory prepared membranes are comparable to that of the cellulose membranes. The fluorinated group had a slightly higher diffusion coefficient with urea than the non-fluorinated group. However, the non-fluorinated membranes had a higher diffusion coefficient by an order of magnitude over the fluorinated membranes for sodium chloride and uric acid.
