ANION SELECTIVITY INDUCTIVE FILM AND ANION SELECTIVITY ELECTRODE

摘要

PROBLEM TO BE SOLVED: To raise stability of selectivity of an anion selectivity electrode based on an anion exchange resin film. ;SOLUTION: Regarding an anion selectivity electrode based on an anion exchange resin film, which is a covalent bond of quaternary ammonium salt to a polymer, an anion for improving selectivity is formed in an entwined condition to an anion exchange resin film as a polymer. Preferably, an anion polymer is formed in the interior of the anion exchange resin film in an entwined condition by polymerizing the anion monomer after impregnating the anion monomer, which becomes the origin of the latter anion polymer, in the former anion exchange resin film. Thus a material containing a cation exchange base contributing to the improvement of selectivity is prevented from eluding and stability of selectivity is raised.;COPYRIGHT: (C)1998,JPO
