摘要：

Supercritical fluid extraction (SFE) of pesticides has been investigated for the possibility of selective extraction between organochlorine (OCPs) and organophosphorus (OPPs) compounds. Three OCPs and OPPs were trapped onto a C-18 Empore(TM) extraction disk prior to SFE with CO2 only and methanol-modified CO2 at various pressures and constant temperature. The results indicate that OCPs can be quantitatively extracted using CO2 only whereas OPPs require a modifier for extraction.
