摘　　要：通过对不同吸附剂的筛选,初步探讨了梨中氟虫脲残留分析—柱层析净化。研究结果表明:梨提取浓缩液过不同类型的吸附剂,所得加标回收率以过中性氧化铝柱和弗罗里硅土柱满足农药残留分析的要求,分别为88.56%和86.58%;硅胶净化效果最差;活性炭对氟虫脲有吸附。中性氧化铝柱和弗罗里硅土柱获得的图谱相似。In this paper, the residue analysis of flufenoxuron in pear was studied by selection of different sorbent. The research indicated that, recoveries of flufenoxuron in pear were 88.56% and 86.58% when cleaned up with neutral Al2O3 column and florisil column. The silica gel column was not fit for flufenoxuron and active carbon adsorb flufenoxuron. The HPLC chromatograms of flufenoxuron in pear cleaned up by neutral Al2O3 and Florisil were similar.
