Abstract

The effects of specific surface area and pore size of dialysis membrane on the dialysis were studied. It was confirmed that the intermittent sampling method(in which any volume of dialyzing solution is sampled intermittently at every moment after any duration of the dialysis experiment) is suitable for the determination of a dialysis coefficient. It was also confirmed that the diffusion coefficient of a electrolyte through membrane is smaller than the free diffusion coefficient though the pore size of dialysis membrane is extremely large.
