摘　　要：建立了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XBridgeC18色谱柱和可变波长紫外检测器,并以水相磷酸盐缓冲体系-乙腈(体积比60∶40)作流动相;流速为0.8mL/min;检测波长为245nm;保留时间为4.72min;线性相关系数为0.9987,回收率在76.2%～108.7%之间,相对标准偏差在0.6%～3.37%之间,对土壤的最低检出限为0.05mg/kg。The ultrasonic-assisted solvent extraction and quantitative analysis of the oxine-copper residues in soil with ion pair of antiphase HPLC was established. This methods 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 245 nm. The residue time was 4.72 minute. The linear correlation of this method was 0.998 7. The recovery rate was 76.2 to 108.7%. Comparatively standard deviation was 0.6 to 3.37%. The detection limits of method was 0.05 mg/kg.
