A continuous-automated method for the determination of nitrite ion using gas-sensing membrane electrode was developed. The pH electrode of tubular PVC membrane type was used as a detector of this system. The slope of linear response of the electrode measured at optimum conditions for the continuous-automated determination of nitrite ion was 63.5 mV/decade. The concentration range of linear response and detection limit were 2.5 × 10-4 ∼ 7.5 × 10-2M and 8.0 × 10-5M, respectively. This detection system was not only less interfering to acidic gas species than other methods but also less time consumable for determination.
