In this experiment protein membrane was used in several measurements. First, after changing the fixed ions of the membrane by soaking it in the solution with different pH, it is confirmed by the membrane potential, that the membrane is stable in neutral salt solution and enables us to find the isoelectric point. Then, the author made an experiment on the diffusion of inorganic salts and amino acids through the membranes, each soaked in pH 6.2 solution, acid and alkaline. The result of the experiment shows that, in the case of membranes soaked in acid or alkaline, the ions, which are charged similary to the fixed ions of the membrane, have smaller diffusion coefficient than those of the membrane soaked in pH 6.2 solution,while the ions which are oppositely charged have larger diffusion coefficient.
