A gas-liquid chromatographic method is described for residues of a synthetic pyrethroid, Sumicidin (alpha-cyano-3-phenoxybenzyl alpha-isopropyl-4-chlorophenylacetate), on cabbage. The plant material is Soxhlet-extracted with hexaneacetone (1+1) and subsequently cleaned up on Florisil with benzene-ethyl acetate (9+1) eluting solvent. Gas-liquid chromatographic analysis was performed on a 0.5 m x 2 mm stainless steel column containing 3% OV-101+3% Apiezon L on 80-100 mesh Gas-Chrom Q, with tritium electron capture detection. Sumicidin recovery was 97% when added at the 0.5 ppm level. Routine Sumicidin residue monitoring data are presented.
本文描述了一种用于检测卷心菜上合成拟除虫菊酯速灭菊酯（α-氰基-3-苯氧基苄基α-异丙基-4-氯苯基乙酸酯）残留量的气液色谱法。将植物材料用己烷 - 丙酮（1 + 1）进行索氏提取，随后在弗罗里硅土柱上进行净化，用苯 - 乙酸乙酯（9 + 1）作为洗脱溶剂。气液色谱分析在一根0.5米×2毫米的不锈钢柱上进行，该柱填充有涂覆在80 - 100目气相色谱担体Q上的3% OV - 101 + 3% 阿皮松L，采用氚电子捕获检测。当添加水平为0.5 ppm时，速灭菊酯的回收率为97%。文中给出了常规的速灭菊酯残留监测数据。
