SOLID-PHASE EXTRACTION IN MULTI-RESIDUE PESTICIDE ANALYSIS OF WATER

The determination of pesticides in water is fundamental to the solutio n of environmental problems as natural waters are usually contaminated with a large number of pesticides, The selection of an isolation and/ or concentration technique depends largely on the class of pesticides to be determined. It is often necessary to determine simultaneously a wide variety of compounds in a water sample. Application of solid-phas e extraction techniques offers a solution. The mechanisms of solid-pha se extraction, types of sorbents and their application to multi-residu e pesticide analysis are reviewed.
