Determination of Organochlorine Pesticide Residues in Tobaccos by Capillary Gas Chromatography

摘要

A simple,rapid,relative reliable method for extraction of 17 Organochlorine pesticides in tobaccos and their determination by capillary gas chromatography was presented.The pesticides were extracted and cleaned-up by a Soxhlet extractor with hexane as extracting solvent.Different methods were compared for the determination of Organochlorine pesticides in tobaccos.The Soxhlet extraction was evaluated for Organochlorine pesticides analyses in tobaccos while liquid-liquid partition and solid phase extraction methods were compared.Of all the extracting methods used,Soxhlet extraction gave the best results.
