Abstract
The objective of this report is clarify the mechanism of electrolyte transfer through dialysis membrane. The usual dialysance DB, which was proposed by E. Klein et al, is valid for nonelectrolytes. However, it has not been investigated if DB was valid for electrolytes, so that experiments were planned to confirm that in our laboratory. It was found that DB was not valid for electrolytes in case of protein solution but valid in case of aqueous solution, because protein was anionic in charge and also impermeable to dialysis membrane. It is necessary to take into account the Donnan effect only in the case of protein solution.
