Special Issue Information

Dear Colleagues,

Fabric phase sorptive extraction (FPSE), a new-generation green sample preparation technique, has drawn considerable interests in recent years among practicing scientists and researchers in many different fields, including analytical chemistry, bioanalytical chemistry, clinical chemistry, food science, environmental chemistry, pharmaceutical chemistry, forensic science, and sports science.

FPSE has uniquely integrated solid phase extraction (exhaustive extraction) and solid phase microextraction (equilibrium extraction) into single, unified sample preparation technology platform. As such, FPSE can be performed in SPE mode, as  well as in direct immersion-SPME mode. However, both the extraction modes offer near exhaustive extraction depending on the logKow of the analyte.  

Unlike conventional sample preparation techniques such as solid phase extraction and solid phase microextraction which only utilize the selectivity of prisine organic polymers or ligands, fabric phase sorptive simultaneously exploits the selectivity of the organic polymer, unique material properies of Si/Ti/Zr chemistries and hydrophilic/hydrophobic properties of the fabric substrate to boost the analyte extraction efficiency.

In addition to substantially simplifying sample preparation, FPSE has eliminated sample pretreatment steps such as filtration, centrifugation, protein precipitation and sample post-treatment steps such as solvent evaporation and sample reconstitution from the sample preparation work-flow.

FPSE opens up a new direction in whole blood analysis without converting into plasma/serum with a far reaching implications in clinical chemistry, metabolomics disease biomarker discovery, phamacokinetics and pharmadynamics studies to name a few.

I take the pleasure to invite you to contribute original research articles and review papers for this Special Issue, ”Advances in Fabric Phase Sorptive Extraction”, which will highlight the advantages of FPSE as a green and simple sample preparation technology over its conventional counterparts.

Fabric phase sorptive extraction (FPSE) has gained notable attention and interest both in batch and automatic mode utilizing advanced sol-gel derived microextraction sorbents and the hydrophobic/hydrophilic properties of fabric substrates. Recently, the innovative on-line fabric disk sorptive extraction (FDSE) has opened new opportunities in the field of automatic sample preparation (preconcentration/separation). A novel sol-gel sorbent based on caprolactone-dimethylsiloxane-caprolactone block polymer comprised of a non-polar dimethylsiloxane and hydrophilic caprolactone as a coating on hydrophobic polyester fabric substrate and its evaluation in an automatic FDSE system coupled with flame atomic absorption spectrometry (FAAS), is presented for the first time. The capabilities of the proposed flow injection system were assessed for trace Cu(II), Ni(II), Zn(II), Pb(II), and Cd(II) determination in urine samples. The method was based on the on-line formation of target analytes with ammonium pyrrolidine dithiocarbamate (APDC) and their retention onto the surface of the fabric disk medium. Methyl isobutyl ketone (MIBK) was used to elute metal–APDC complexes directly into the nebulizer-burner system of FAAS. For 90 s of preconcentration time, enhancement factors of 250, 130, 185, and 36 and detection limits (3 s) of 0.15, 0.41, 1.62, and 0.49 μg L−1 were obtained for Cu(II), Ni(II), Pb(II), and Cd(II), respectively. For 30 s of preconcentration time, an enhancement factor of 49 and a detection limit of 0.12 μg L−1 was achieved for Zn(II) determination. The precision, expressed as relative standard deviation (RSD), was lower than 3.5% for all metals. The accuracy of the proposed method was sufficient and evaluated by analyzing certified reference materials and biological samples. Full article

Fabric phase sorptive extraction (FPSE) is a novel and green sample preparation technique introduced in 2014. FPSE utilizes a natural or synthetic permeable and flexible fabric substrate chemically coated with a sol-gel organic-inorganic hybrid sorbent in the form of ultra-thin coating, which leads to a fast and sensitive micro-extraction device. The flexible FPSE requires no modification of samples and allows direct extraction of analytes. Sol-gel sorbent-coated FPSE media possesses high chemical, solvent, and thermal stability due to the strong covalent bonding between the substrate and the sol-gel sorbent. Therefore, any elution solvent can be used in a small volume, which achieves a high pre-concentration factor without requiring any solvent evaporation and sample reconstitution step. Taking into consideration the complexity of the samples and the need of further minimization and automation, some new, alternative modes of the FPSE have also been developed. Therefore, FPSE has attracted the interest of the scientific community that deals with sample pre-treatment and has been successfully applied for the extraction and determination of many analytes in environmental samples as well as in food and biological samples. The objective of the current review is to present and classify the applications of FPSE according to different sample categories and to briefly show the progress, advantages, and the main principles of the proposed technique.

The occurrence of organic micropollutants (OMPs) in the environment is a global concern due to their potential ecological risks. Several studies have shown that some OMPs are widely detected in environmental matrices such as surface water and sewage. Wastewater treatment plants (WWTPs) have received international attention over past decades because they are considered the greatest source of aquatic environmental contamination by anthropogenic micropollutants. Intensive sampling and analysis have been globally made to improve understanding of the occurrence, behavior and fate of OMPs in WWTPs using different types of analytical approach. Recently, special awareness has been devoted to developing new effective strategies to extract the micropollutants of wastewater. In particular, microextraction protocols have gained popularity because of their simplicity, low cost and in-field application for environmental analysis. Among these, fabric phase sorptive extraction (FPSE) is reported as an excellent approach due to its properties, not only reducing the required time but also employing minor solvent volume. In this overview, we summarize the results obtained by the Research Group of Environmental Chemical Analysis of the University of Las Palmas de Gran Canaria (Spain) using this technique. Its aim is to show the potential of FPSE for the extraction of some micropollutants, such as personal care products (benzotriazole ultraviolet stabilizers (BUVSs)) and pharmaceuticals (steroid hormones and cytostatic compounds) in different liquid samples, prior to their determination by liquid chromatography.
