摘要
本文采用气相色谱(GC)附ECD检测器,对蔬菜中百菌清进行定量分析。分别比较弗罗里硅土、活性炭和凝胶渗透色谱(GPC)三种方法去除蔬菜样品色素,确定采用凝胶渗透净化色谱法(GPC)去除蔬菜样品中色素等杂质,样品处理过程简便,回收率较高。
A method for the determination of Chlorothalonil in vegetable by GC, The sample was cleaned up with Florisil ,Activated Carbon and GPC, and determined by gas chromatography and electroncapture detection （GC - ECD）. The GC -GPC method was simple,rapid and accurate.
