摘　　要：【目的】采用高效液相色谱仪，建立25％灭·喹·氟磺胺微乳剂3种有效成分同时测定的分析方法。【方法】该方法选用乙腈-0．5％磷酸水溶液为流动相，215nm为检测波长，可同时对灭草松、精喹禾灵、氟磺胺草醚含量进行测定。【结果】在质量浓度0．1-50mg／L范围内，灭草松、精喹禾灵、氟磺胺草醚的线性相关系数分别为1．0000、1．0000、0．9999，回收率分别为87．29％。94．96％、88．13％-95．12％、81．72％-92．83％，相对标准偏差分别为1．70％、1．35％、2．35％，仪器最低检出限分别为2．2、8．3、10．0μg／L。【结论】该方法可用于这3种成分的复配制剂含量标定，也可用于3种成分的残留量测定。[Aims] The aims were to establish a quantitative analysis method for bentazone- quizalofop, fomesafen 25% ME. [Methods] The simultaneous determination of three active ingredients in the pesticide formulation was conducted by HPLC with the mix,re of acetonitrile and 0.5% phosphoric acid aqueous solution as mobile phase at 215 rim. [Results] When the concentration was in the range of 0.1-50 mg/L, the linear correlation coefficients for bentazone, quizalofop and fomesafen were 1.0000, 1.0000 and 0.9999, the average recoveries were 87.29-94.96, 88.13-95.12 and 81.72-92.83%, the variation coefficients were 1.70, 1.35 and 2.35%, and the limit of determination were 2.2, 8.3 and 10.0 μg/L, respectively. [Conclusions] The method can be used for the determination of the contents of the 3 compound comnonents, and also can be used for the determination of the residues of the 3 comr-onents.
