摘要：

A rapid, sensitive and reliable HPLC method was developed and validated for the determination of imidacloprid residue in water at different pH and in soil. Quantification was performed by reversed phase HPLC system equipped with UV detector. The limit of quantification (LOQ) was found to be 0.02 mg/kg in soil and 0.02 mg/L in water. The limit of detection (LOD) was 0.006 mg/kg in soil and 0.006 mg/L in water. Recoveries for imidacloprid were 95.18%, 94.66%, 95.27% and 94.78% in black, red, sandy loam and clay soils, respectively. Recoveries for imidacloprid from water were 96.86%, 86.14%, and 92.34% at pH values of 4, 7, and 9, respectively.
