Open publisher page 0 citations

Abstract

Organochlorine pesticides in soil were extracted by microwave extraction,and it was finally analyzed with GC-ECD.The detection limit was between 0.020 μg/kg to 0.051 μg/kg,while in precision testing the relative standard deviations was between 4.15% to 5.32% with recovery rate stayed between 85.4% and 96.0%.
