Solid phase techniques in the extraction of pesticides and related compounds from foods and soils

Abstract

AbstractThe application of SPE technology to the isolation of pesticides and related compounds from food and soils has grown enormously in the last decade. Much of this growth has been due to the relative ease of sample handling and the wide range of solid supports currently available for a variety of applications. The aim of this review is to present the methods for solid phase extraction (SPE) of pesticide residues from soils and foods. There are three main areas according to the type of approach used to handle the sample: solid phase extraction, solid phase clean‐up (SPC), and matrix solid phase dispersion (MSPD). This review covers milk products, fatty foods, fruits, vegetables, and soils. Solid phase materials are discussed in each case in terms of reversed bonded‐phase silica sorbents (C18, C8, C2, etc.) and polar sorbents (alumina, Florisil, and silica).
