| Abstract: | The residual contents of Buprofezin, Fenpropathrin, Fenvalerate and Bifenthrin in tea were determined by GC with ECD. The results showed that their detection limits were 0.01 mg/kg, 0.01 mg/kg,0. 05 mg/kg and 0.01 mg/kg,respectively. Their recovery rates were 86.0-100. 5%, 84. 7-99.3% ,83. 3%-100. 2% and 87. 3%-100. 5% ,respectively,and their variation coefficients were in 2. 1-4.6%. So the accuracy,sensibility and precision of this method was higher. |
