【摘要】：[目的]采用液相色譜法,建立肟草酮的儀器分析方法及在環(huán)境樣品中的殘留檢測(cè)方法。[方法]使用XTerra~汶 RP18柱,以乙腈-水(體積比65∶35,含萬(wàn)分之二的磷酸)為流動(dòng)相,在UV 254.4 nm下外標(biāo)法定量分析。[結(jié)果]采用丙酮為提取劑,用磷酸調(diào)節(jié)pH值至3,乙酸乙酯萃取的方法,水、土壤和沉積物中平均回收率分別為96.0%~98.2%、85.3%~96.2%、89.1%~91.3%,相對(duì)標(biāo)準(zhǔn)偏差為1.0%~8.0%。[結(jié)論]該方法分析速度快、靈敏度高、重現(xiàn)性好,適用于肟草酮的環(huán)境樣品中的快速檢測(cè)。
[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.
