Determination of phenols in gas emissions from industry using GC/SPME

Abstract

A quantitative gas chromatographic method is proposed for the determination of phenolics
vapours in gas emissions from industry (guaiacol, m-cresol, 2,4-dimethylphenol, p-thymol, phenol).
The method is based on the gas absorption by alkaline solution with successive extraction of
determinate compounds by solid phase microextraction (SPME) with direct immersion. The analysis is
performed on open tubular macro column with unpolar stationary phase.
The target phenols were quantified in range from 0.1 mg/m3 to 100 mg/m3 with a satisfactory
relative standard deviation for all the analytes (RSD = 20%).
The method is suitable for determination of the analytes in drinking and surface waters
