Title: Analytical Methods for Bromothalonil Residues in Apple and Soil
Abstract: A method was established for determining bromothalonil residues in apple and soil.Residues were extracted with toluene,acetone and dichloromethane,cleaned up by SPE cartridge,and determined with GC equipped by ECD detector.The average recoveries and coefficient of variations of the method were 80.6 to 96.7%,2.0 to 4.0% for apple samples,and 80.4 to 105.1%,1.9 to 8.4% for soil sample,respectively.The minimum detectable amount of bromothalonil were 2.0×10 -11 g,and the minimum detectable concentrations were 0.03 mg/kg,respectively.These results showed that the method accords with demands of residue analysis of pesticide.
