CHLORINE ION SENSOR, ITS MANUFACTURING METHOD, AND BIOCHEMICAL AUTOMATIC ANALYTICAL DEVICE USING THE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a chlorine ion sensitive film for improving ion selectivity, and to provide a manufacturing method of the chlorine ion sensitive film.;SOLUTION: The chlorine ion sensitive film comprises a first process for dipping an anion exchange resin film into solution, where 1-naphtylamine 4-sodium sulfonate is dissolved into a solvent; and a second process, where the anion exchange resin film in which 1-naphtylamine 4-sodium sulfonate is dipped, is dipped into a mixed liquid of a compound having a carbonyl group and an inorganic acid for generating the condensate of 1-naphtylamine 4-sodium sulfonate and the compound having the carbonyl group, thus improving selectivity that is the characteristic as an ion sensor, and hence obtaining high reliability.;COPYRIGHT: (C)2004,JPO&NCIPI
