Response mechanism of a membrane made of trioctylmethylammonium chloride (TOMA) to ethanol was studied. The response of the TOMA membrane to ethanol increased linearly with increasing ethanol concentration (0 – 20 %) at constant KCl concentration. The slope of response to ethanol was -1.73 (mV/ethanol %) using the multiple regression analysis (0 – 20 % ethanol, 1 – 100 mM KCI). The value of this slope calculated using the transfer activity coefficient of chloride ion from water to ethanol showed a good agreement with the experimental value. On the other hand, the results obtained in AgCl and anion exchange membrane disagreed with the theoretical values.
