Optimization of SPE/GC/HPLC Analytical Procedure for Determination of Phenol, Quinones, and Carboxylic Acids in Water Samples

Abstract

Chromatographic techniques are among the most useful analytical methods. Gas and liquid chromatography were used in the analysis of some organic compounds: phenol, hydroquinone, benzoquinone, and maleic and fumaric acids. The analytical way for the determination of these compounds in water samples was investigated. Solid-phase extraction (SPE) technique was used on the sample preparation step, different divinylbenzene-based sorbents were applied. Calibration curves of given compounds were linear over the ranges: 50–500 μ g/mL for phenol and its acetic derivatives, 50–1500 μ g/mL for benzoquinone in GC analysis, and 50–250 μ g/mL for phenol, 40–1000 μ g/mL for hydroquinone, and 4–4500 μ g/mL for carboxylic acids in HPLC analysis. The LOD and LOQ of proposed analytical procedure were in the ranges of LOD: 0.042–23.83 μ g/mL; LOQ: 0.138–78.64 μ g/mL.
