摘　　要：本实验建立了同时分离检测饲料中三嗪类除草剂（莠灭净、莠去津）、三唑类杀菌剂（戊唑醇、联苯三唑醇、烯唑醇）和菊酯类杀虫剂（胺菊酯、三氟氯氰菊酯、四氟甲醚菊酯）三类（8种）农药的高效液相色谱（HPLC）-二极管阵列检测器（DAD）7）方法。结果表明，8种农药在10min内实现了基线分离，线性相关系数为0．9996～0．9999，检出限为0．003～0．02bg／mL。该方法可用于饲料及其他样品中三类农药残留的高效、灵敏、快速检测。A high performance liquid chromatography(HPLC)- diode array detector(DVD)method was developed for the determination of eight pesticides including ametryn,atrazine,tebuconazole,bitertanol,diniconazole,tetramethrin,cyhalothrin and dimefluthrin in feed samples.The results showed that complete sparation of the eight pesticides was achieved within 10 min,the detection limits were 0.003 ~ 0.02 μg/m L.The method was efficient,sensitive and fast,which could determine simultaneously the three classes of pesticide residues in feed or other samples.
