摘要
本文报道了用高效液相色谱仪测定桑叶中多菌灵残留量的分析方法。样品用酸性甲醇振荡提取,二氯甲烷萃取纯化;样品浓度为10、5、0.5ppm时,方法回收率范围、标准差、变异系数分别为88.14~98.94%、1.01~2.58、1.05~2.82%;添加平均回收率为86.98~95.58%,标准差和变异系数为0.96~3.47、1.00~3.99%。
This paper reports that residue analysis method of the carbendazim in White Mulberry leaves by High-Performance Liquid Chromatography(HPLC).Leaves sample were extracted with acid methanol, the extracted solution was puriflied methylene chloride.Recovery range, standard and variant coefficient of the method is 88.14-98.94%, 1.01-2.58 and 1.05-2.82%,respectively.Additive recovery from 86.98-95.58%, standard and variant coefficient is 0.96—3.47%, 1.00—3.99% separately.
