PROBLEM TO BE SOLVED: To improve ion selectivity. SOLUTION: In a method, with chlorine ion sensitive film, an anion exchange resin is dipped into a solution where metaphenylenediamine is dissolved into a solvent as a first process. An anion exchange resin film where metaphenylenediamine is impregnated is dipped into a mixed liquid with formaldehyde and hydrochloric acid to generate the condensed object between metaphenylenediamine and formaldehyde as a second process. In this manner, ion selectivity and stability are improved, thus achieving a reliable hydrochloric acid ion sensor. |
