摘　　要：建立了黄瓜和土壤中喹啉铜的超声波辅助溶剂提取-反相离子对高效液相色谱法的残留分析方法,该方法使用XBridge C18色谱柱和可变波长紫外检测器,并以水相磷酸盐缓冲溶液—乙腈(体积比为60∶40)作流动相;流速为0.8 mL/min;检测波长为250 nm;保留时间为4.71 min;该方法的准确度、精密度及灵敏度均满足农药残留分析的要求。This article mainly established the analysis method to extract the oxine-copper residues in cucumber and soil with ion pair of antiphase HPLC and Ultrasonic-assisted solvent. This method mainly uses XBridge C18 column and UV detector by using waters phase of phosphatic buffered solution/acetonitrile （60 ： 40,by vol） as mobile phase with 0.8 mL/min flow ratio and UV detection at 250 nm. The residue time was 4.71 minute. Accuracy,precision,and sensitivity of the method all satisfy the demands of pesticide residue analysis.
