为了探索方法,我们用人工模拟法对蜂蜜中有机氯农药残留量分析方法进行了初探。结果表明:用石油醚——二甲基甲酰胺(DMF)分配方法提取,硫酸净化较适宜于蜂蜜中有机氯农药残留量分析,现将此方法介绍如下: 一、主要仪器与试剂 1.气相色谱仪(Uarian GC—3760)ECD Ni~(63) 2.锥形分液漏斗 1000毫升 3.烧杯 250、500毫升 4.石油醚分析纯重蒸(60~90℃) 5.二甲基甲酰胺(DMF) 化学纯
In order to explore the method, we used artificial simulation method to study the method of organochlorine pesticide residue analysis in honey. The results showed that the method of petroleum ether-dimethylformamide (DMF) extraction method, sulfuric acid purification is more suitable for analysis of organochlorine pesticide residues in honey, now this method is described as follows: First, the main equipment and reagents 1. Gas phase Chromatography (Uarian GC-3760) ECD Ni ~ (63) 2. Conical Separation funnel 1000 ml 3. Beaker 250,500 ml 4. Petrol ether Analysis Pure re-steaming (60-90 ° C) 5. Dimethyl Amide (DMF) is chemically pure
