Abstract:
In this work, poly(styrene-co-divinylbenzene) or PS-DVB monolithic adsorbent was synthesized as a bead to extract twelve phenols from water sample. Determination of the target analytes were performed by using gas chromatography with mass spectrometry (GC-MS). In the synthesis, styrene and divinylbenzene, and dibenzoyl peroxide were used as the monomer and initiator, respectively, while decanol and tetrahydrofuran were added to improve porosity during the polymerization. Morphology of synthetic material showed an interconnected spherical shape of monolith structure of averagely 2 µm diameter. Due to the uniform and thoroughly interconnected particles within the macropore network of PS-DVB bead, it was used for extraction of the target analytes from water sample. In this study, several parameters affecting the extraction efficiency, such as extraction time, sample volume, sample pH, salt concentration, desorption time and number of monolithic bead, were evaluated. This method provided good linear ranges of all phenols between 0.1-50 mg L-1 with a correlation coefficient greater than 0.99. The limit of detections were found in a range of 1.46-227.32 µg L-1 . The recoveries of fortified water spiked concentration at 20 mg L-1 were in the range of 50.13 to 105.32%. %RSDs of repeatability and reproducibility of this method were in the range of 0.51-2.99 and 0.14-5.44, respectively. The developed method was successfully applied to extract phenols in real waters sample with no matrix effect. The recoveries of all spiked samples were found in the range of 50.76-109.07%, 50.83-97.64%, 50.07-107.32% and 50.54-108.15 % in water station, canal water, tap water and bottled water, respectively.
