The method was established to analysis the oxine-copper with ion pair of antiphase HPLC and Ultrasonic-assisted solvent extraction methods.

建立了喹啉铜原药的超声波辅助溶剂提取-反相离子对高效液相色谱法的分析方法。

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.

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 C5 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 0.9987. 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.
