A silica-based MCM-41 mesoporous material functionalized with cyanopropyl groups has been synthesized by cocondensation, characterized and applied to preconcentrate six parabens and three UV filters in river and swimming-pool waters. The analytes were quantified by ultra-high performance liquid chromatography-tandem mass spectrometry, according to the Directive 96/23/EC. Even though matrix effect was negligible, quantification in river water samples with the standard addition approach improved the recoveries obtained using solvent-based and even with matrixmatched calibration. The method quantification limits in river water samples were 0.05 ng/mL for 2,4-dihydroxybenzophenone and 0.01 ng/mL for the rest. Recoveries, evaluated for a concentration level of 0.5 ng/L, were in the range 93.5-107.6% for parabens and in the range 64.2-85.8% for UV filters, with relative standard deviations intraday ≤10.2 and 10.8%, respectively. This parameter, evaluated for a concentration level of 0.1 ng/L, ranged between 98.3 and 110.4% for parabens and between 61.9 and 89.9% for UV filters, with relative standard deviation intraday ≤15.3 and 15.5%, respectively. The two UV filters with lower recoveries were the most affected by the addition of sodium chloride. River and swimming pool waters were analyzed and all the personal care products were found in the swimming pool water, whereas only methylparaben was detected in the river water.

“…A literature research on determination of OPPs pesticides in water samples was conducted to assess the proposed technique with some other previously reported methods. As tabulated in Table II, the developed MSPE method offers recovery to be highly comparable with solid phase extraction (SPE) [5], dispersive solid phase extraction (DSPE) [18]) and solid phase microextraction (SPME) [19] methods. Magnetic Solid Phase extraction (MSPE) proposed method offers a simplicity and minimizing the usage of organic solvent.…”

“…Hence, it is indispensable to develop simple and sensitive pre concentration steps which are capable of detecting their trace residue concentrations in environmental samples. Various pre-treatment methods have been used for the separation OPPs in various matrices including solid phase extraction (SPE) [5], solid phase microextraction (SPME) [6], dispersive solid phase extraction (DSPE) [7] and micro-solid phase extraction (µ-SPE) [8].…”

The present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples. The resultant sorbent material was physicochemically and morphologically characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and N2 adsorption analysis. OPPs pesticides extraction efficiency of two sorbents were evaluated through magnetic solid phase extraction (MSPE) using high performance liquid chromatography with ultraviolet detector (HPLC/UV). The main parameters affecting the sorbent efficiency namely extraction time and desorption solvent were optimized. Comparatively, Fe3O4 -SBA-15 achieved excellent percent recovery (97.5%) compared to the Fe3O4 -MCM-41 (87.1%) under optimum condition respectively. The result appealed that the Fe3O4 -SBA-15 composite was efficient sorbent with good capability for the preconcentration of selected OPPs from water samples.AThe present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples.

“…Mesoporous silica materials, particularly for SBA-15 and MCM-41, provide a highly organized and orderly pore structure that allows selective adsorption of different molecule sizes during sample pretreatment [22,23]. The size of the pores can also be modified relative to the size of adsorbed molecules.…”

A mesoporous silica was functionalized by carbon nanotubes to enhance the extraction performance. The mesoporous material was coated on stainless steel wires, and three wires were inserted inside of a polyetheretherketone tube for in‐tube solid‐phase microextraction. The tube was coupled to high‐performance liquid chromatography with diode array detection to obtain online analytical system, then its extraction performance was evaluated using eight polycyclic aromatic hydrocarbons as the targets. In order to good sensitivity and accuracy, four conditions were optimized such as sampling volume, sampling rate, methanol content in the sample, and desorption time. Under the optimum conditions, an online analytical method was established and exhibited low limits of detection from 0.005 to 0.050 µg/L, wide linear range of 0.016‐20.00 µg/L with acceptable correlation coefficients in 0.9921‐0.9999, as well as large enrichment factors in the range of 311‐2412. The method was successfully applied to determine trace polycyclic aromatic hydrocarbons in some real water samples including, two kinds of bottled water, tap water, and river water, a few polycyclic aromatic hydrocarbons were detected but none quantified in these samples.
