摘要
Sample preparation is a very important and essential step in environmental analysis. A brief overview of modern sample preparation such as solvent based methods, sorptive, membrane - assisted and instrumental methods which have been recently applied to extract and preconcentrate organic analytes from different environmental matrices, is presented. The different requirements of each methodology (and its modes of implementation), especially the extraction phase, are discussed. Instead of a comprehensive list of applications, the implementation of these techniques with selected examples covering mainly research published the last three years is highlighted.
