%X 建立了多种水果和饮料中氟嘧菌酯和嘧螨酯残留的超高效液相色谱测定方法.样品用乙酸乙酯-环己烷(体积比为1∶1)超声波萃取,凝胶渗透色谱法净化,超高效液相色谱-二极管阵列检测器检测,外标法定量.采用 BEH C18色谱柱(50 mm×2.1 mm,1.7 μm),流动相为水-乙腈(体积比为3∶7),流速为0.3 mL/min,柱温为40 ℃,紫外检测波长为251 nm.实验结果表明:氟嘧菌酯和嘧螨酯在0.05～2 mg/L 范围内线性关系良好(r>0.999),在不同的基质中添加3个浓度水平(0.01,0.05,0.1 mg/kg)的氟嘧菌酯和嘧螨酯,两者的回收率均在82.60% ～101.11%之间,相对标准偏差为5.4% ～15.3% ;检出限不大于6 μg/kg,定量限不大于20 μg/kg.
