description | In this study, a simple, effective, and sensitive method has been developed for the quantitative residue analysis of cyhalofop-butyl and its metabolite cyhalofop acid in water and soil when kept under laboratory conditions. The content of cyholofop-butyl and cyhalofop acid in water and soil was analyzed by first purifying the compounds through liquid-liquid extraction and partitioning followed by Silica gel (adsorption) chromatography. Upon the completion of the purification step the residual levels were monitored through high-performance liquid chromatography (HPLC) using a UV absorbance detector. The recoveries of cyhalofop-butyl from three replicates spiked at two different concentrations ranged from 82.5 to 100.0% and from 66.7 to 97.9% in water and soil, respectively. The limit of detection and minimum detection level of cyhalofop-butyl in water and soil was 0.02 ppm and 10 ng, respectively. The recoveries of cyhalofop acid ranged from 80.7 to 104.8% in water and from 76.9 to 98.1 % in soil. The limit of detection of cyhalofop acid was 0.005 ppm in water and 0.01 ppm in soil, while the minimum detection level was 2 ng both in water and soil. The half-live of cyhalofop-butyl was 4.14 and 6.6 days in water and soil, respectively. The method was successfully applied to evaluate cyhalofop-butyl residues in water and soil applied aj. 30% emulsion, oil in water (EW) product. 실험실 내 조건에서, 물과 토양 중 cyhalofop-butyl과 그 대사물질인 cyhalofop acid를 위한 잔류분석법이 고감도에서도 간단하고 매우 효과적으로 개발되었다. 물과 토양 중 cyhalofop-butyl과 cyhalofop acid를 분석하기 위하여 액액분별추출과 silica gel chromatographic 정제를 수행하였으며 HPLC-UV를 이용하여 정성/정량하였다. cyhalofop-butyl의 회수율은 2 가지 농도에서 3 반복 수행하여 각각 82.5-100.0%와 66.7-97.9%이었고, 검출한계와 최소검출량은 두 시료에서 모두 0.02 ppm과 10 ng이었다. Cyhalofop acid의 회수율은 물과 토양에서 각각 80.7-104.8%와 76.9-98.1%이 었으며, 검출한계는 각각 0.005 ppm과 0.01 ppm이었고 최소검출량은 두 시료에서 모두 2 ng이었다. Cyhalofop-butyl의 반감기는 물과 토양에서 각각 4.14와 6.6 day였다. 개발되어진 본 시험법은 cyhalofop-butyl의 30% 유탁제를 처리한 물과 토양에서 그 잔류량을 분석하기 위하여 성공적으로 적용되었다. |
