Abstract	(Bakelite-A)-(2,2'-Bipyridine)-Ni(Ⅱ) Nitrate 착물 막전극이 질산 이온 선택성 막전극이 됨을 확인하였다. 이 막전극은 수소 이온이나 2가 및 3가 음이온에는 감응하지 아니하였고, 특히 이 막전극의 수명, 감응 농도 범위, 감응 시간 및 이온 선택성 등 전기 화학적 성질과 착물 리간드의 유성도 크기 사이의 관계를 비료 고찰하였고, 또한 막의 최적 조건의 착물조성 구조로부터 막의 이온교환 메카니즘을 고찰하였다. (Bakelite-A)-(2,2'-Bipyridine)-Ni(Ⅱ) Nitrate complexes were tested as ion exchanger for nitrate ion-selective electrode. The experimentally observed selectivity and electrode characteristics were relatively in good agreement with the exchanger lipophilicity in the membrane phase. Based on chemical composition, mechanisms for exchange with nitrate ion and internal electrical conduction were postulated. Analytical application to the determination of nitrate were studied.
