“…Although there are a number of published studies where the retention properties of hypercrosslinked resins have been evaluated,11, 21–23 it should be pointed out that the method used in the present study has not been used previously. The approach used here is pertinent to the analysis of, for example, environmental samples, and has been adopted to allow the facile transfer to the analysis of real samples where similar analyte concentrations arise.…”

Two different gel-type resins have been prepared by suspension polymerization using 2 wt % divinylbenzene (DVB) with either p-vinylbenzyl chloride (pVBC) or a mixture of VBC isomers (similar to 70% m-; similar to 30% p-). Significant difference in the chlorine content was observed, which was attributed to a more favored hydrolysis process when p-VBC was used. The presence of hydroxyl groups has been confirmed by elemental microanalytical data and solid-state C-13 cross-polarization/magic angle spinning (CP-MAS) nuclear magnetic resonance (NMR) spectra. Hypercrosslinked resins were prepared from both gel-type precursors by treatment with FeCl3, in 1,2-dichloroethane (DCE) at 80 degrees C. The resultant resins showed differences in specific surface area and degree of hydrophilicity. The performance of the hypercrosslinked resins was evaluated in solid-phase extraction (SPE) of polar compounds, and better results were obtained for the hypercrosslinked resin prepared from p-VBC that combines a relatively high specific surface area (908 m(2) g(-1)) and somewhat higher oxygen content (3.96 wt % O)

“…Therefore, it is very important to develop simple and rapid analytical methods for the determination of dihydroxybenzene isomers. At present, various methods have been used, including chromatography [2,3], spectrophotometry [4,5], and electrochemical method [6,7]. In the last few years, the electrochemical method has received more attention due to its high efficiency, low cost, and easy operation.…”

The voltammetric behaviors of dihydroxybenzene isomers were studied at an ordered mesoporous carbonmodified glassy carbon (OMC/GC) electrode. Compared to the bare electrode, the electrocatalytic activity of the modified electrode toward dihydroxybenzenes is evidenced by the increase of the peak current and the decrease of the peak separation (DE p ) in 0.1 M pH 5.0 phosphate buffer solution (PBS). Furthermore, at the OMC/GC-modified electrode, the three isomers could be separated entirely. The oxidation peak potential difference between hydroquinone and catechol is 154 mV, whereas that difference between catechol, and resorcinol is 370 mV. In the amperometric detection, the peak currents of dihydroxybenzene increased linearly with increasing dihydroxybenzene contents. The detection limits were 7.6 9 10 -8 M, 1.0 9 10 -7 M, 9.0 9 10 -8 M for hydroquinone, catechol and resorcinol, respectively, which are the lowest values ever reported for dihydroxybenzene isomers. These make OMC/GC electrode a promising candidate for the simultaneous determination of isomers.

“…At present, numerous methods have been developed for detecting HQ, for example, chromatography [1][2][3][4], spectrophotometry [5][6][7][8], and electrochemical methods [9,10]. However, chromatography and spectrophotometry methods are time-consuming and require complex pre-treatment.…”
