摘要：

The successful application of supercritical fluid extraction for environmental samples requires that the extraction conditions determined for spiked samples must be optimized in order to overcome the solute-matrix interactions that are responsible for lower recoveries in real samples compared to spiked samples. In this optimization, preserving the selectivity of exraction is a key factor. This principle is demonstrated by the extraction of PCBs from different matrices. Some other environmental examples also illustrate the importance of matrix-solute interactions.
