The proton which forms the solid-state high-molecular

摘要

PROBLEM TO BE SOLVED: To pluralistically evaluate the deteriorated degree by measuring the continuous deteriorated degree of a fluorine resin-based polymer electrolytic film and one factor with which a sampling work of the fluorine resin-based polymer electrolytic film used to the treatment of tritium-containing water and polluted with radioactive materials is excluded and the measurement at the distance place is realized.;SOLUTION: The deteriorated degree of the fluorine resin-based polymer electrolytic film is pluralistically evaluated from only observation of fluorine ion quantity by utilizing that two indexes of the strength and the conductive characteristic showing the characteristic of the principle chain and index evaluating the characteristic of the side chain in the fluorine resin-based polymer electrolytic film having a proton (H⁺) conductivity, have high correlation with the fluorine ion quantity eluted in the circulated water with the deterioration.;COPYRIGHT: (C)2006,JPO&NCIPI
