Abstract
본 발명은 염화이온센서의 전극에 구비되는 염화이온 선택성 막을 형성하기 위한 조성물 및 이것을 사용하여 염화이온 선택성 막을 형성하는 방법에 관한 것이다. 본 발명의 조성물은 실리콘 러버, 이온 선택성 물질로서 테트라데실트리메틸암모늄 클로라이드 1∼20중량% 및 유용성 가소제 0∼40중량%로 이루어진다. 본 발명의 조성물을 사용하여 형성한 염화이온 선택성 막은 고체상 전극 표면에 형성되는 경우에는 고체상 전극 표면에 대한 접착력과 전기 화학적 성질이 우수하여 염화이온에 대한 감응성의 문제 및 짧은 수명의 문제를 해소하여 염화이온 센서의 소형화를 가능하게 한다. 또한 본 발명에 따른 조성물로 형성된 염화이온 선택성 막이 적용되는 재래식 전극 또는 고체상 전극은 이들을 구비한 염화이온 센서를 사용하여 생체물질 중 염화이온의 정량분석시 살리실레이트이온에 의한 방해작용을 받지 않을 뿐만 아니라 pH 5.5∼10.5 범위의 생체물질에서 수산화 이온에 의한 방해작용을 받지 않음으로써, 측정 신뢰도를 한층 더 향상시킬 수 있다는 효과가 있다.The present invention relates to a composition for forming a chloride ion selective membrane provided on an electrode of a chloride ion sensor and a method of forming a chloride ion selective membrane using the same. The composition of the present invention consists of silicone rubber, 1-20% by weight of tetradecyltrimethylammonium chloride as an ion-selective material and 0-40% by weight of an oil-soluble plasticizer. When the chloride ion selective membrane formed using the composition of the present invention is formed on the surface of the solid phase electrode, the chloride ion selective membrane has excellent adhesion and electrochemical properties to the surface of the solid phase electrode, thereby eliminating the problem of sensitivity to chloride ion and the problem of short life. Allows the miniaturization of the ion sensor. In addition, the conventional electrode or solid-state electrode to which the chloride ion selective membrane formed of the composition according to the present invention is applied does not have an interference effect by salicylate ion in the quantitative analysis of chloride ion in a biological material using a chloride ion sensor provided therewith. However, by not being disturbed by hydroxide ions in the biological material in the pH range of 5.5 to 10.5, there is an effect that the measurement reliability can be further improved.
