“…Due to the unique features of silica, it can be used to allow the adsorption of small molecules as well as the large ones by size-exclusion mechanism. 38 In addition, silica shows a high surface area and low-cost, which makes this material an attractive sorbent to dSPE. 39 Even this small amount (50 mg) of silica was demonstrated to be an effective and cheap way to remove the coextracted fatty acids and other matrix components from the soybean extract prior to the analysis of DTC fungicides without any loss of CS 2.…”

Food matrices consist of many components with different physical and chemical properties that may influence instrumental robustness. The soybean contains fatty coextractives which may have a deleterious effect on the gas chromatography (GC) system. In this study, the efficiencies of PSA, C 18 OH, C 18 , silica, aluminum oxide, and Florisil, as dSPE clean-up sorbents, were evaluated by the high-performance liquid chromatography (HPLC) diode-array detector and evaporative light-scattering detector analysis. The dithiocarbamates in soybean samples are determined as CS 2 using acidic hydrolysis and isooctane partitioning, followed by GC-PFPD and GC-ITD-MS analyses. The linearity of the analytical curves, the instrument limit of detection matrix effects, the trueness and precision, and the method limit of quantification (LOQ) were assessed in the validation study. Milled soybean was spiked with thiram solution at three concentration levels (corresponding to 0.05, 0.1, and 0.5 mg CS 2 kg −1 ) for recovery determination. Silica appeared to be an effective and cheap sorbent to remove coextracted matrix components without causing any CS 2 losses. Recoveries were in the range of 68−91%, with relative standard deviations ≤ 8.7%. The method LOQ was 0.05 mg CS 2 kg −1 , and both GC-ITD-MS and GC-PFPD systems appeared to be appropriate and complementary to determine dithiocarbamate residues in soybean extracts.

Extensive use of organophosphorus pesticides in agriculture leads to adverse effects to the environment and human health. Sample preparation is compulsory to enrich target analytes prior to detection as they often exist at trace levels and this step is critical as it determines the concentration of pollutants present in samples. The selection of a suitable extraction method is of great importance. The analytical performance of the extraction methods is influenced by the selection of sorbents as sorbents play a vital role in the sensitivity and selectivity of an analytical method. To date, numerous sorbent materials have been developed to cater to the needs of selective and sensitive pesticides’ detection. Comprehensive details pertaining to extraction methods, developed sorbents, and analytical performance are provided. This review intended to provide a general overview on different extraction techniques and sorbents that have been developed in the last 10 years for organophosphorus pesticides’ determinations in food and water samples.

“…This sorbent was successfully evaluated in the extraction of a group of acidic pharmaceuticals from environmental water samples, benefiting from both the reversed-phase and the SAX interactions between the sorbent and the analytes. Pellicer-Castell et al [56] prepared different mesoporous silica sorbents (Universidad Valencia materials -UVM-), including pure, modified with cyclodextrins and doped with Ti and Fe (to tune the porosity of the original sorbent). Of these, a sorbent doped with Ti (UVM7-Ti25) presented the best porous properties, and thus, provided the best results for the extraction of a group of organophosphorus compounds from environmental water samples.…”

This review provides an overview of the most recent developments involving materials for solid-phase extraction applied to determine organic contaminants. It mainly concerns polymer-based sorbents that include high-capacity, as well as selective sorbents, inorganic-based sorbents that include those prepared using sol-gel technology along with structured porous materials based on inorganic species, and carbon nanomaterials, such as graphene and carbon nanotubes. Different types of magnetic nanoparticles coated with these materials are also reviewed. Such materials, together with their main morphological and chemical features, are described, as are some representative examples of their application as solid-phase extraction materials to extract organic compounds from different types of samples, including environmental water, biological fluids, and food.
