Abstract	모세관 컬럼을 사용한 기체크로마토그래피로 19종 유기염소제 농약의 분리를 검토하였고, 쌀에 첨가한 농약들의 회수율을 구하여 봄으로써 실제분석에 대한 본 방법의 응용 가능성을 조사하였다. SE-30과 OV-17모세관 컬럼의 분리를 비교하여 본 결과 OV-17 컬럼(25m × 0.20mm, 0.27μm 두께)으로 분리가 잘되고 있으며, splitless방식으로 주입한 농약들의 머무른 시간과 봉우리 면적에 대한 상대표준 편차가 최대로 0.16%와 8.2%이었다. 쌀에 첨가된 농약의 회수율은 대부분 85%이상이었고 분석 결과에 대한 상대표준편차가 가장 큰 것이 11.4%로서 흔적량의 잔류농약분석에서 비교적 정밀도가 좋음을 확인하였다. The separation of 19 organochlorine pesticides was studied by capillary column gas chromatography. The applicability of this method to the fresh rice was investigated. Comparison of the resolution of pesticides by OV-17 and SE-30 capillary columns revealed that OV-17 column (25m × 0.20mm, 0.27μm thickness) showed better resolution. The relative standard deviations (RSD) for their retention times and peak areas obtained by splitless injection mode were within 0.16% and 8.2%, respectively. The recoveries of pesticides spiked in fresh rice were mostly over 85% and their RSDS did not exceed 11.4%.
