The electrodialysis with ion-exchange membranes is a very useful method for separating an objective amino acid from mixed amino acids. The values of the limiting current density in the electrodialysis for various kinds of amino acids and pH were measured in this work. It was found that the values of limiting current density decreased with increasing the molecular weight of amino acids, viz., glycine (Gly), alanine (Ala), and arginine (Arg). It was evident that the relationship between the concentration of total ions in the feed solution and the limiting current density showed a straight line which passed through the origin. The value of the limiting current density of amino acids is smaller than that of inorganic ions.
