Abstract

The residual analysis and half-life time of imidazole fungicide prochloraz in soils (silty clay) were investigated by gas chromatography equipped electron capture detector (GC-ECD). The soil samples were extracted acetone/hexane(1:1) solvent and analyzed after separated by $LC-NH_2$ Sep-Pak solid column. Linear sensitivity of standard calibration curve was Y = 268.8600X + 0.0664, $R^2=0.9998$ between 0.05~1.00 ng. The detection limit was 0.02 mg/L and the average recoveries were 94.5~97.3% from the standard additional experiments with 0.10 and 0.40 mg/L. The half-life time was 24.4 days in room laboratory and 7.6 days in the field test soil.

Imidzole계 살균제 prochloraz의 토양(미사질식토) 잔류량 및 반감기를 전자포획검출기를 이용한 기페크로마토그래피로 분석하였다. 토양시료는 acetone/hexane (1:1) 용매로 추출하였고, $LC-NH_2$ Sep-Pak 고체컬럼으로 분리하였다. 표준검정곡선의 감응함수는 0.05~1.00 ng 범위에서 Y = 268.8600X + 0.0664, $R^2=0.9998$ 이었다. 검출한계는 0.02 mg/mL 이었고, 회수율은 0.10 mg/L의 경우 97.3%, 0.40 mg/L의 경우 94.5% 이었다. 반감기는 실내토양에서 24.4일, 포장토양에서 7.6일 이었다.
