Determination on Residual Quantity of Methomyi, Diflubenzuron and Cartap in Tea by HPLC-MS/MS
Abstract：The residual quantity of methomyl, diflubenzuron and cartap in tea was determined by HPLC-MS/MS. The results showed that good linearities were obtained for three pesticides at the concentration of 0.1-10 btg/mL with correlation coefficients more than 0. 999. The recovery ratios were 82%-105%, the relative standard deviations(RSD) were 0.8% -5.3% and the detection limits were 0. 002-0. 016 mg/kg. The method was quick, sim ple, sensitive and accurate, and it could satisfy the request of the determination of organophosphorus pesticides residue in tea.
