The development of new methods of analysis ensuring high accuracy in the determination of toxicants over a wide range of concentrations is necessary for the reliable analytical quality control of natural and purified waste water. Electroanalytical methods allow the determination of a great many environmentally hazardous organic compounds, including phenol and its derivatives. The method of stripping voltammetry has been progressing very rapidly in recent years. This method offers selectivity and low detection limits in determining organic compounds. Classical methods of potentiometry and amperometry are also useful in the routine analytical control of phenol-containing water. The determination limits for phenols can be lowered by means of extraction preconcentration with water-soluble polar organic solvents. The proposed hybrid methods are rapid, which is particularly important for large-scale analytical control, and they permit immediate determination at the places of sampling. The aim of this work is to theoretically justify both the choice of hydrophilic extractants for preconcentration and the conditions of electroanalytical determination of phenols over a wide range of concentrations directly in a nonaqueous concentrate.
