摘要
Residue levels were estimated using HPLC-UV detection. Samples were hydrated and extracted using acetonitrile. Analytical linearity in the range of 0.02 to 2.0 mg/kg was excellent with a determination coefficient (R (2)) of 1.0. Recovery at levels of 0.2 and 1.0 mg/kg ranged from 89.9 to 94.6% with a relative standard deviation %26lt; 5%. Sufficient sensitivity was achieved. The limits of detection and quantification were 0.006 and 0.02 mg/kg, respectively. The method was successfully applied to analysis of field samples. This method was effective and can be used for routine analysis of etofenprox in tea samples at low concentrations.
