Abstract

PURPOSE: To improve response speed of anion selective electrode of high selectivity by using alkyl nitro phenyl ethers of high dielectric constants as a plasticizer of sensitive membrane.
CONSTITUTION: In a sensitive membrane comprising dispersing high molecular weight quaternary ammonium compound having 1 to 4 alkyl chains of C7-16 in a high polymer membrane such as of poly(vinyl chloride) membrane, an alkyl phenyl ether compound of a dielectric constant 10 or higher having alkyl of C5-10, e.g., ocyl-o-nitro phenyl ether, is dispersed as a plasticizer at 1 to 20% in weight concentration.
