Abstract

Ion-exchange techniques are widely used for separation of ionic species, purification of water, chemical analysis of trace elements, and desalination of sea water. A membrane process characterized by an electrical field orthogonal to ion-exchange membranes, so called electrodialysis is useful for the separation of ionic species. Although the solution including additives such as pH controlled buffer, there are many ionic species generated by dissociation, which makes it difficult to analyze the ion-exchange reaction and the membrane transport phenomena. This paper is addressed to elucidate the following remarks: (1) Model analysis of sorption characteristics for carboxylic acids by an anion-exchange membrane. (2) Permeation behavior of mono-, di-, and tricarboxylic acids in Electrodialysis. (3) Separation of rare-metal elements by means on electrodialysis accompanied by metal substitution reaction. (4) Recovery of EDTA and Cu from EDTA-Cu solution by use of electrodialysis accompanied by electrochemical reaction.<br>
