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.
