摘  要：
[目的]建立一种便捷、准确、灵敏的方法测定环境水样中痕量的有机磷农药。[方法]采用全自动固相萃取进行样品净化及浓缩,对儋州松涛水库和海口南渡江河水中7种有机磷农药进行测定。[结果]在优化的试验条件下,7种目标化合物色谱峰分离良好,以地表水为基质,7种有机磷农药在加标质量浓度分别为0.20、0.24和0.48μμg/L时回收率为69.4%～106%,相对标准偏差为2.21%～8.65%(n=5),方法检出限分别为0.02～0.04μg/L,定量下限为0.08～0.16μg/L。[结论]该方法简便快速、重现性好、净化效果好且通用性强,可用于海南河库水环境中有机磷农药残留的分析。

摘  要：
[Objective] The research aimed to set up a simple,accurate and sensitive determination method for the trace organophosphorous pesticides in environmental water samples.[Method] Using automatic solid-phase extraction,the samples were cleaned and concentrated.Seven kinds of organophosphorous pesticides in the water of Danzhou Songtao Reservoir and Haikou Nandu river were determined.[Result] Under the optimized experimental conditions,the chromatographic peaks of 7 kinds of organophosphorous pesticides were separated well.With surface water as matrices,the recovery rate of 7 kinds of organophosphorous pesticides at the addition mass concentration of 0.20,0.24 and 0.48 μg/L was 69.4%-106% and RSD was 2.21%-8.65%(n=5),the detection limit of the method was 0.02-0.04 μg/L and quantitative lower limit was 0.08-0.16 μg/L.[Conclusion] The method is simple and rapid,and it has good reproducibility,good purification effect and strong universality.And it can be used in the residual analysis of organophosphorous pesticides in environmental water of Hainan river bank.
