摘要: 研究并建立了氟虫腈(Fipronil)在辣椒和白菜中的残留分析方法。样品以乙腈提取,中性氧化铝(含活性炭)柱层析净化,气相色谱测定。氟虫腈的最小检测量为2×10-13g,最低检测浓度为25ng/kg。辣椒中氟虫腈的添加回收率(0.005~0.5mg/kg)为81.20%~90.58%,变异系数是3.94%~9.46%,白菜中氟虫腈的添加回收率(0.005~0.5mg/kg)为82.48%~89.35%,变异系数为2.77%~9.21%。方法的准确性、灵敏度均达到农药残留分析的要求。

Abstract: Gas chromatography was used to analyze the residue of fipronil in pepper and Chinese cabbage. Residues of Fipronil were extracted from pepper and Chinese cabbage with acetonitrile, cleaned up by column chromatography of Al2O3, and determined with GLC equipped by ECD.The average recoveries and coefficient of variations of the method were 81.20%~ 90.58%, 3.94%~9.46% for pepper, and 82.48%~89.35%, 2.77%~9.21% for Chinese cabbage, respectively. The minimum detectable amount of fipronil was 2×10-13g , the minimum detectable concentration of fipronil in the samples of tomato and soil was 25ng/kg. These results showed that the method was in accordaue with demands of residue analysis of pesticide.
