Theory and recent applications of coacervate-based extraction techniques

In recent years, development of sample-preparation techniques with significant advantages over conventional methods for the extraction of organic compounds from different samples became increasingly important. Coacervates emerged as promising environment-friendly alternatives for sample preparation. This review covers the basic theory of coacervates and summarizes recent applications (2010-15) of coacervates for preconcentration of organic compounds, metal ions and nanoparticles from various types of sample.
