Supercritical fluid extraction (SFE) procedures for pesticide residue analysis are reviewed and discussed. A variety of applications were classified, on matrices such as fruits, vegetables, soils, biological tissues, and other materials. Emphasis is placed on analysis of samples with a high water content containing polar pesticides, with particular attention paid to the multiresidue analyses.
The work presented is a preliminary study for the development of a method for the extraction of pesticides from wax samples by means of superficial fluid extraction. The novelty of the study is the direct extraction of the pesticides from raw wool wax without any cleanup, as direct extraction has been considered almost impossible by many authors.
