| 摘 要： | 确立了一套检测水生植物中阿特拉津残留量的方法.样品经石油醚-二氯甲烷混合液振荡萃取,经硅镁吸附剂层析柱净化后,采用气相色谱-电子捕获检测器检测水生植物中阿特拉津的残留量.该方法在0.062～1.0mg/L范围内峰面积与阿特拉津浓度的线性关系良好(r~2=0.9993).在0.5mg/L、1.0mg/L、1.5mg/L ...

| Abstract: | A method was developed for the determination of Atrazine residues in aquatic plants using gas chromatography(GC).The aquatic plant samples were extracted with dichloromethane-petroleum ether system and cleaned up by Florisil on a solid phase extraction column.The cleaned extract was analyzed by GC with ECD monitor.The linear ranges of the calibration curves for Atrazine were from 0.0065 to 1.0 mg/L.The limits of detection of the method was 0.01 mg/kg.The recoveries ranged from 86.78% to 94.87% with the RSD ... |
