ABSTRACT:
A method for purifying and concentrating organic matters by employing an amphoteric ion-exchange membrane which is made of a ternary block copolymer consisting of a macromolecule poly A.sup.- having cation-exchange group, a macromolecule poly B.sup.+ having anion-exchange group and a macromolecule poly C having no ion-exchange group and allows sodium chloride to permeate at a concentration not lower than 100% of that in the starting aqueous solution when a pressure of 50 kg/cm.sup.2 is given to the starting aqueous solution of sodium chloride of 0.01 g/dl and by allowing inorganic salts to permeate selectively from an aqueous solution of the organic compounds containing the inorganic salts with giving an increased pressure thereto.
