Abstract
지난 수십년 동안, 환경오염물질에 대한 광학적 전기화학적 검출 방법에 관한 다양한 연구가 진행되었다. 최근에는 저렴하고, 장치가 불필요한 육안 식별 가능한 환경색센서가 개발되고 있다. 시각적 정성분석은 대상물질에 대한 즉각적인 정보를 제공하여, 실시간 현장 분석이 가능하게 해준다. 또한 정량분석이 가능한 색센서에 대한 관심도 높아지고 있다. 환경색센서는 기상의 VOC, 액상의 중금속 분석용으로 주로 개발되고 있다. 이에 본 총설에서는 다양한 환경색센서의 활용분야를 살펴보고, 기존 색센서의 문제점을 파악한 다음 환경색센서 기술의 발전방향에 관하여 전망하였다. The electrochemical or optical sensors for environmental pollutants are developed over the past several years. Nowadays, the development of colorimetric sensing is particularly challenging since it requires no equipment at all as color changes can be detected by the naked eye. Visual detection can give immediate qualitative information and is becoming increasingly appreciated in terms of quantitative analysis. In addition, simple colorimetric-sensor have shown useful in the detection, identification, and quantification of volatile organic compounds(VOC) in gas phase or heavy metal ion in aqueous phase. In this review, we investigated the wide applications and some drawbacks of colorimetric-sensors. And thus, we try to suggest the methodologies of development approach of multi-functional and reversible colorimetric-sensor.
