클로로페놀 12종을 폐수로부터 LPME법을 사용하여 추출하였고, GC/MS로 분석하였다. 최적의 추출조건을 확립하기 위해 추출용매의 종류, 시료의 양, pH, 염석 효과, 플런저 왕복 횟수 및 속도를 고려하여 최적의 조건을 확립하였다. 그 결과, 직선성이 0.9913에서 0.9999를 가지는 12가지의 검정곡선을 얻을 수 있었고, 검출한계와 정량한계도 2,3,4,5-테트라클로로페놀과 펜타클로로페놀(0.05-500 ng/mL)을 제외하고 0.05~10.0 ng/mL범위에서 얻을 수 있었다. 실제 폐수에서 4-클로로-3-메틸페놀(784 ng/mL)을 확인할 수 있었다.
Twelve chlorophenols (CPs) were extracted by liquid phase microextraction (LPME) from the industrial waste-water and analyzed by GC/MS. To establish the optimal conditions, species of extraction solvent, sample amount, pH of sample, salting out effect, a number of sampling and plunger movement speed were investigated. As a result, the linearities of calibaration curves ranged from 0.9913 to 0.9999, while LODs and LOQs were from 0.05 to 10.0 ng/mL except 2,3,4,5-tetrachlorophenol and pentachlorophenol. Using this method, 4-chloro-3-methylphenol confirmed from waste water at the concentration of 784 ng/mL. The method can be applicable to detect chlorophenols from industrial waste-water.
