摘要

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, 0.27￥ìm 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%.
