“… 45 Therefore, the detection and monitoring of Sb have been compulsory. Various analytical approaches such as UV-Vis spectrophotometer, 46,47 capillary electrophoresis, 48 spectrofluorimetry, 49 atomic absorption spectrometry, 50–54 laser-induced fluorescence, 55 inductively coupled plasma-optical emission spectrometry (ICP-OES), 42,56 high-performance liquid chromatography coupled with hydride generation-atomic fluorescence spectrometry (HPLC-HG-AFS), 57,58 etc. have been reported for the determination of antimony (Sb 3+ ) in addition to the various electrochemical methods.…”

“…To obtain the highest extraction efficiency for capsaicinoids, the influence of the different variables affecting both the adsorption and desorption steps in the DMSPE procedure was evaluated using the supernatant obtained in the treatment of 500 μL of serum (spiked with the analytes at 0.1 mg L −1 ) with 1 mL AcN and diluted to 10 mL with water. Since the nature of the sorbent magnetic material is determinant in preconcentration efficiency, several magnetic materials were synthesized following previously published procedures: oleic acid [22], silver [23], (3-aminopropyl)triethoxysilane (APTS) [24], cellulose [25], GO [26], polypyrrole (PPy) [26], MWCNTs@PPy [26], and MWCNTs [21], all of them magnetized with Fe 3 O 4 . Possible interactions between capsaicinoids and oleic acid sorbent due to long hydrocarbon chains contained in both structures led us to try Fe 3 O 4 @oleic acid.…”

A new analytical method based on the use of dispersive magnetic solid-phase extraction (DMSPE) is described for the preconcentration of capsaicin (CAP), dihydrocapsaicin (DCAP), and N-vanillylnonanamide (PCAP) from human serum samples. The influence of several experimental factors affecting the adsorption (nature and amount of magnetic material, adsorption time, and pH) and desorption (nature of solvent, its volume and desorption time) steps was studied. Among seven different nanomaterials studied, the best results were obtained using magnetic multiwalled carbon nanotubes, which were characterized by means of spectrometry- and microscopy-based techniques. Analyses were performed by ultra-high-performance liquid chromatography with quadrupole-time-of-flight mass spectrometry using electrospray ionization in positive mode (UHPLC-ESI-Q-TOF-MS). The developed method was validated by obtaining several parameters, including linearity (0.3–300 μg L−1 range), and limits of detection which were 0.1, 0.15, and 0.17 μg L−1 for CAP, DCAP, and PCAP, respectively. The repeatability of the method, expressed as relative standard deviation (RSD, n = 7), varied from 3.4 to 11%. The serum samples were also studied through a non-targeted approach in a search for capsaicinoid metabolites and related compounds. With this objective, the fragmentation pathway of this family of compounds was initially studied and a strategy was established for the identification of novel or less studied capsaicinoid-derived compounds.

“…In addition, Sb is used as a catalyst in the production of poly(ethylene terephthalate) (PET), which is used in plastic bottles [ 8 ]. These PET bottles are used as packages for beverages and water [ 9 , 10 ]. As such, Sb is often detected in bottled water and beverages because of leakage from PET through storage [ 11 , 12 ].…”

Magnetic Ion Imprinted Polymers (MIIPs) for Selective Extraction and Preconcentration of Sb(III) from Environmental Matrices

Antimony(III) is a rare element whose chemical and toxicological properties bear a resemblance to those of arsenic. As a result, the presence of Sb(III) in water might have adverse effects on human health and aquatic life. However, Sb(III) exists at very ultra-trace levels which may be difficult for direct quantification. Therefore, there is a need to develop efficient and reliable selective extraction and preconcentration of Sb(III) in water systems. Herein, a selective extraction and preconcentration of trace Sb(III) from environmental samples was achieved using ultrasound assisted magnetic solid-phase extraction (UA-MSPE) based on magnetic Sb(III) ion imprinted polymer-Fe3O4@SiO2@CNFs nanocomposite as an adsorbent. The amount of antimony in samples was determined using inductively coupled plasma optical emission spectrometry (ICP-OES). The UA-MSPE conditions were investigated using fractional factorial design and response surface methodology based on central composite design. The Sb(III)-IIP sorbent displayed excellent selectivity towards Sb(III) as compared to NIIP adsorbent. Under optimised conditions, the enrichment factor, limit of detection (LOD) and limit of quantification (LOQ) of UA-MSPE/ICP-OES for Sb(III) were 71.3, 0.13 µg L−1 and 0.44 µg L−1, respectively. The intra-day and inter-day precision expressed as relative standard deviations (%RSDs, n = 10 and n = 5) were 2.4 and 4.7, respectively. The proposed analytical method was applied in the determination of trace Sb(III) in environmental samples. Furthermore, the accuracy of the method was evaluated using spiked recovery experiments and the percentage recoveries ranged from 95–98.3%.
