Abstract:Based on the standard BHC and DDT environmental analysis approach of soil,eight BHC and DDT in pesticides were extracted by using ultrasonic wave probe extraction and acetone-hexane mixed solvent,which were purified by Florisil column followed with N concentration.It was finally analyzed by means of capillary gas chromatography.The detec-tion limit of the method is 0.033~0.120 μg/kg,the blank recovery is 83.9%~115.0%,and RSD is 4.5%~11.3%.
Keywords:BHC  DDT  Soil  GC
