Abstract

A method for the determination of anionic solutes such as phenol, cresols, and xylenols present in industrial effluents has been developed. It is based on microextraction using two miscible phases followed by demixing of the phases by the addition of ammonium sulfate. The extraction properties of 2โ€propanol were examined and the procedures were optimized. High resolution gas chromatographyโ€“mass spectrometry in the selected ion monitoring mode was used as a separation and quantitation technique. This method is rapid and precise and allows detection limits of 1 ฮผg L^โˆ’1^ to be easily obtainable employing a 50 mL water sample.
