气相色谱法测定水和废水中的10种有机氯农药

Determination of 10 Organochlorine Pesticides in Water and Waste Water by Gas Chromatographic

采用电子俘获检测器(ECD)气相色谱法测定水和废水中的10种有机氯农药。方法在5μg/L^80μg/L质量浓度范围内线性关系良好,样品检出限为0.00004μg/L^0.00019μg/L,标准溶液平行测定的RSD为0.87%~3.59%,废水样品加标回收率为82.3%~109%。

A gas chromatographic with electron capture detector(ECD)method has been developed for determination of 10 organochlo⁃rine pesticides in water and waste water.Linearity was abided by the range of 5μg/L^80μg/L.Detection limits ranged from 0.00004μg/L to 0.00019μg/L.RSD of standard solution parallel determination ranged from 0.87%to 3.59%,Spiked recoveries of waste water ranged from 82.3%to 109%.
