Latest Patents

Fujita holds a patent for a "Method for purifying and concentrating organic matters." This method employs an amphoteric ion-exchange membrane made of a ternary block copolymer. The copolymer consists of a macromolecule poly A.sup.- with a cation-exchange group, a macromolecule poly B.sup.+ with an anion-exchange group, and a macromolecule poly C that has no ion-exchange group. The method 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 applied. Additionally, it enables the selective permeation of inorganic salts from an aqueous solution containing organic compounds.
