摘要
建立用HPLC-荧光检测法测定果蔬饮料中克百威、甲萘威残留量的方法。试样用甲醇-二氯甲烷(1:99,V/V)提取,取一定量有机相过氨基柱、浓缩、定容,外标法定量。该方法的检出限为克百威0.002mg/kg、甲萘威0.0008mg/kg,加标回收率在77.1%～94.5%之间,测定的相对标准偏差在1.3%～9.0%之间。
A method for the determination of carbofuran and carbaryl in fruit and vegetable juice was established by high performance liquid chromatography （HPLC）. The samples were extracted with the mixture of methanol and dichloromethane （1：99, V/V）. After cleanup with amino column and concentration to constant volume, the carbofuran and carbaryl extracted into the organic phase was analyzed quantificationally by external standard method. The results showed that the detection limits of the two pesticides were 0.002 mg/kg and 0.0008 mg/kg, and their average spike recoveries range from 77.1% to 94.5% with the relative satandard deviation of 1.3% to 9.0%.
