- 中文摘要: The goal of this study was to develop an analytical method to determine the organochlorine pesticides residues in milk. The samples were loaded onto the self-packed diatomaceous earth columns, then eluted with 25 mL solvent mixture of n-hexane-acetone-ethyl acetate (4+2+1, v/v/v). After collection and concentration, the extracts were cleaned up by the C18 solid-phase extraction cartridges. Gas chromatograph/electron capture detector was used for determination. The average recoveries of milk which were spiked with 10 ng/mL of a-BHC, lindane, heptachlor, dieldrin, p,p’-DDD, and p,p’-DDT were above 92%. Limits of detection between 0.5-1.8 ng/mL were achieved.
