Abstract

To develop an approach for rapid detection of imidacloprid residue in pear,conventional high performance liquid chromatograph(HPLC) was modified.When ODS C18 was used as mobile phase with acetonitirle ∶ water of 40 ∶ 60 (v ∶v),and the wavelength for detection was set at 268 nm,the recovery rates of imidacloprid residue in pear were high from 83.3% to 116.6%,with low relative standard deviation sell than 5.06%.This approach was optimal in detecting imidacloprid rapidly,accurately and effectively.
