“…IRA96 was chosen since it is composed by the same styrene-divinylbenzene polymeric matrix of non-polar XAD4 and XAD16 resins but it contains also polyamine groups, which confer a certain polarity to the adsorbent and, importantly, can strongly interfere with acids through anion exchange process; Isolute ENV+ was chosen since it is a non-polar hydroxylated polystyrene-divinylbenzene copolymer which was found to effectively adsorb low molecular weight phenolic compounds from an aqueous solution [48].…”

“…Such extraction procedures as liquid -liquid extraction (LLE) [5], solidphase microextraction (SPME) [6], SPE [7], and stir bar sorptive extraction (SBSE) [8,9] have been developed for the separation and enrichment of phenols. However, large amount of poisonously organic solvent would be used in LLE [5], low extractive capacity for SPME [6], inconvenient derivatization procedure should be taken in SBSE using PDMS as coating [8,9], the variability and low recoveries of the SPE has been noted [10].…”

Development and validation of stir bar sorptive extraction of polar phenols in water followed by HPLC separation in poly(vinylpyrrolididonedivinylbenzene) monolith An effective and simple method for polar phenols in water matrix was developed by using stir bar sorptive extraction (SBSE) based on a hydrophilic poly(vinylpyrrolididone-divinylbenzene) (VPDB) monolithic material and HPLC analysis. To achieve optimum extraction performance for phenols, several parameters, including extraction and desorption time, desorption solvent, pH value, and ionic strength of sample matrix, were investigated. Under the optimized experimental conditions, eight phenols were directly enriched from water samples and analyzed by HPLC-DAD. The detection limits (S/N = 3) and quantification limits (S/N = 10) of the proposed method for the target compounds were achieved within the range of 0.72 -1.37 and 2.40 -4.27 ng/mL from spiked water, respectively. Recoveries of eight phenolic compounds were found in the range of 55.2 -95.9%. The calibration curves showed the linearity ranging from 5 to 150 ng/mL with linear regression coefficient R 2 values above 0.98. Method repeatability presented as intra-and interday precisions were also found with the RSDs less than 4.10 and 7.61%, respectively. The distribution coefficients between VPDB and water (K VPDB/W ) for phenolic compounds were also calculated and compared with K O/W . Finally, the proposed method was successfully applied to the determination of the target compounds in tap water, sea water and wastewater samples.

“…1) [3,4,6]. Many of the reported methods reduce the remaining water volume on the phase material after the extraction step by actively drying the sorbent [4,5,[7][8][9][10][11][12]. The reasons for this step are manifold [13,14].…”

Occurrence of residual water within disk-based solid-phase extraction and its effect on GC-MS measurement of organic extracts of environmental samples

Solid-phase extraction (SPE) is a widespread and powerful sample preparation technique in many analytical areas. Many of the used methods reduce residual water during sample preparation by drying the phase material. Despite the importance of this step, hardly any study deals specifically with the drying process, and if so, only few aspects are mentioned. The present study is the first systematic investigation of the drying process using SPE disks, including the influence of process parameters on the amount of residual water and its consequences for subsequent elution and gas chromatography-mass spectrometry (GC-MS) analysis. The following points were investigated in detail: (1) the change of pressure and volume flow during the drying process, (2) the remaining amount of water at different drying times for different SPE materials, (3) the influence of suspended particulate matter on the drying process and (4) the effects of the residual water on the elution step by using different organic solvents. The study shows that the volume of residual water in the SPE disk is affected by the fixation of the sorbent, the phase material, the amount of sorbent, the pumping settings and the duration of the drying process. Furthermore, systematic investigations demonstrate the influence of residual water on the GC-MS analysis and show analytical interferences only for a few of the investigated analytes. All results suggest that more problems in SPE GC-MS methods are caused by residual water than previously assumed.
