Solid-phase Extraction Pretreatment Technique and Analytic Methods of Organochlorine Pesticides

Solid-phase extraction (SPE) has been widely used in environmental sample preparation.The basic mode,method principle,sorbent types of SPE and its two formats in common use (SPE cartridge and SPE disk) are described.The paper also introduces solid-phase microextraction (SPME) which is developed from the conventional SPE.The comprehensive applications of the several methods of SPE,GC and mass spectrometry (MS) and so on to the analysis of residual organochlorine pesticides (OCPs) in environmental samples are also reviewed.
