摘要:
A specific chromatography with packed glass column for determining the residue of cyhalothrin and fenvalerate in tomato jam has been set-up in the analysis process. The method has a good resolution and sensitivity. The average recoveries are 90.5 and 94.0% respectively, and the coefficients of variation are 3.8 and 1.1% respectively, and the detected lowest concentrations are 0.002 and 0.001 mg/kg respectively, for the two pesticides.
