摘要
研究了用HPLC-紫外检测器检测香菇中多菌灵留的方法,通过在提取液中加有机酸,用氨水定容将多菌灵醋酸盐转化为多菌灵等方法提高前处理的回收率,同时使多菌灵在色谱柱中与杂质实现分离,方法的5倍信噪比的检出限为0.2mg/kg,添加回收率为85.6%～123.1%,变异系数为3.5%～8.0%。
A HPLC method for determination of carbendazim residue in mushroom was investin-gated.The results showed that the detection limit was 0.2mg/kg,the recoveries were 85.6%～ 123.1%,the coefficients of variation were 3.5%～8.0% respectively.
