摘要
试验了废水中的丙溴磷气相色谱分析方法。以大口径毛细管柱分离废水中的丙溴磷 ,分别采用氮磷检测器(NPD)和电子捕获检测器 (ECD)检测 ,得到了良好的分离效果和较高的灵敏度 ,方法检测限为 0 .0 0 2mg/L(绝对检测量最低可达 2 pg ,NPD)和 0 .0 0 0 8mg/L(绝对检测量最低可达 0 .8pg ,ECD)。该方法中 ,采用双柱双检测器 ,排除了误检和其他物质的干扰 。
Analytical method for profenofos in wastewater by GC was researched. Profenofos was separated in large caliber capillary column, and detected with NPD and ECD. The detection limit was 0.002 mg/L( the lowest absolute detection quantity can reached 2 pg, NPD) and 0.000 8 mg/L( the lowest absolute detection quantity can reached 0.8 pg, ECD). In this method, the use of two column and two detectors can eliminate the disturbance of other materials and guarantee the analytical result's reliability.
