| Abstract: | The residues of four pesticides, namely, carbendazol, imidacloprid, phoxim and diflubenzuron, in pomelo were determined by high performance liquid chromatography. The optimized chromatographic conditions were as follows： the chromatographic column： ZORBAX Eclipse XDB-C18; the grain size： 5.0 μm, 4.6 mm ×250 mm;the mobile phase： methanol： water=-75 ： 25 （V ： V）; the current speed： 1.0 mL/min;the detected wavelength： 280 nm. The recovery rate of the detection method was 70% ~ 130% and the relative standard deviation was smaller than 5%. The detection results showed that the residues of four pesticides, namely, carbendazol, imidacloprid, phoxim and diflubenzuron, in pomelo all did not exceed the standard. |
