ResumoThe restricted availability of water sources suitable for consumption and high costs for obtaining potable water has caused an increase of the conscience concerning the use.Thus, there is a high demand for "environmentally safe methods" which are according to the principles of Green Chemistry.Moreover, these methods should be able to provide reliable results for the analysis of water quality for various pollutants, such as phenol.In this work, greener alternatives for sample preparation for phenol determination in aqueous matrices are presented, which include: liquid phase microextraction, solid phase microextraction, flow analysis, cloud point extraction and aqueous two-phase systems.
