| 摘 要： | 建立了水中阿特拉津固相萃取-高效液相色谱分析方法(SPE-HPLC),并对流动相配比、流速、DAD检测波长和SPE小柱的选择等条件进行了研究,获得了最佳色谱条件:以WatersOASISTMC18SPE柱富集水中阿特拉津,乙酸乙酯作为洗脱剂,以配比为甲醇:水=4∶1的混合溶剂作流动相,流速为0.4mL/min,在222nm波长下以DAD为检测器进行分析。该方法的线性范围为0.10～2.00mg/L,方法检测限为1.0μg/L,自来水加标平均回收率为94%。所建立的方法适用于测定水中的阿特拉津。

| Abstract: | An analytical method for determination of Atrazine in water by solid-phase extraction and liquid chromatography (SPE-HPLC) was developed, with linear range of 0.10~2.00mg/L and detection limit of 1.0μg/L for Atrazine. The recovery of Atrazine was 94% in tap water. Results showed that the proposed method is effective for the determination of Atrazine in water. |
