【摘要】：[目的]采用液相色谱法,建立肟草酮的仪器分析方法及在环境样品中的残留检测方法。[方法]使用XTerra~汶 RP18柱,以乙腈-水(体积比65∶35,含万分之二的磷酸)为流动相,在UV 254.4 nm下外标法定量分析。[结果]采用丙酮为提取剂,用磷酸调节pH值至3,乙酸乙酯萃取的方法,水、土壤和沉积物中平均回收率分别为96.0%~98.2%、85.3%~96.2%、89.1%~91.3%,相对标准偏差为1.0%~8.0%。[结论]该方法分析速度快、灵敏度高、重现性好,适用于肟草酮的环境样品中的快速检测。
[Abstract]:[objective] to establish an instrumental method for the determination of oxoxifen and its residue in environmental samples by liquid chromatography. [methods] the XTerra~ column was used and the mobile phase was acetonitrile-water (65 脳 35 v / v, containing 2/10000 phosphoric acid). The quantitative analysis was carried out by external standard method under UV 254.4 nm. [results] the average recoveries in water, soil and sediment were 96.0% ~ 98.2%, 85.3% ~ 96.2% and 89.1% ~ 91.3%, respectively, when acetone was used to adjust pH value to 3 with phosphoric acid and ethyl acetate was extracted from water, soil and sediment. The relative standard deviation is 1.0% to 8.0%. [conclusion] the method is rapid, sensitive and reproducible. It is suitable for the rapid determination of oxoxifen in environmental samples.
