Abstract Molecular imprinting-based solid-phase extraction (MI-SPE) has been in the spotlight to improve the recognition selectivity and detection sensitivity. MI-SPE provides a powerful tool for chemo/bioanalysis in complex matrices and meanwhile, benefits from distinguished advantages such as easy operation, high throughput, low cost, high selectivity and durability. This review proposed the recent advances in molecular imprinting concerning novel preparation strategies of molecularly imprinte...

Abstract Hydrophobic aerogels were used to remove three types of persistent organic pollutants: pharmaceutical drugs (i.e. doxorubicin [DOX], paclitaxel [TAX]), phthalates (diethyl phthalate [DEP]), and hydrophilic rhodamine dye (RhB) from synthetic and real wastewaters, using Lumira granular aerogel from Cabot activated with EtOH (ET-GAG). The hydrophobic silica aerogel was characterized by X-ray diffraction (XRD), High-Resolution Transmission Electron Microscopy (HRTEM), Brunauer–Emmet–Teller ...

Abstract Molecular imprinting of highly porous silica aerogels is reported for the first time and the selective adsorption of methylxanthines and polycyclic aromatic hydrocarbons (PAHs) has been investigated. The adsorption onto surface-functionalized caffeine-imprinted silica aerogels showed the phenyl-functionalized materials to have a higher adsorption capacity than others. The characterization of imprinted and non-imprinted materials confirmed the removal of the template molecules. The speci...

Abstract Due to the growing problem of cancer diseases, cytostatic drugs have become a great environmental threat. Their main sources are hospital effluents, household discharge and drug manufacturers. As these compounds are not removed during wastewater treatment with sufficient efficiency, they are found in the surface, ground and drinking water in quantities up to 2.12 × 10−4 mg/l. The current knowledge about their harmful influence on humans does not indicate a significant risk to the health...

Silica aerogel with high surface area was prepared by an acid-base two-step catalytic sol-gel method under ambient pressure drying. It was coated onto stainless steel wires as an extraction phase, then three wires were filled into a polyetheretherketone tube for forming an in-tube solid-phase microextraction device. Combined with high performance liquid chromatography, the extraction device was assessed and it exhibited better extraction ability for polycyclic aromatic hydrocarbons than estrogen...

Abstract The silica aerogel was synthesized by simple and cost-effective sol-gel process under ambient pressure drying. The wet gel was modified by using trimethylchlorosilane (TMCS) as silylating agent. The prepared aerogel was characterized by X-ray diffractometer (XRD), thermogravimetric and differential thermal analyzer (TG-DTA), Fourier transform infrared spectrometer (FT-IR), Brunauer-Emmett-Teller (BET) analyzer, field emission scanning electron microscope (FE-SEM) and Ultraviolet-Visible...

Abstract In this work, novel dummy molecularly imprinted polymers (DMIP) with propanamide as a dummy template molecule were prepared based on a green synthesis strategy of less consumption of hazardous/organic reagents and at mild conditions for magnetic solid-phase extraction (MSPE) of acrylamide in biscuit samples, followed by high performance liquid chromatography (HPLC) determination. The resultant DMIP was well characterized by FT-IR, SEM, TEM and VSM, exhibiting uniform nanoscale coreshell...

An effective and reliable method, magnetic solid phase extraction based on magnetic silica aerogels, has been developed and used for the enrichment of 3 pyrethroid insecticides (including fenpropathrin, lambda-cyhalothrin and cypermethrin) from juices and tea beverages. The magnetic silica aerogels were successfully synthesized by an acid–base two-step catalytic sol–gel method using tetraethylorthosilicate (TEOS) as a precursor solution, and characterized. Several influencing factors that could ...

Abstract To improve the extraction performance and mechanical property, a bipyridyl ionic liquid-hybridized silica aerogel was synthesized, and explored as the solid-phase microextraction (SPME) coating. Due to the embedding of the bipyridyl ionic liquid in silica aerogel via the covalent bond, the hybridized material not only provided the three-dimensional and porous structure of the aerogel, and it also possessed good extraction performance of the ionic liquid. Based on the π–π interaction bet...

Abstract A novel sorbent material, gold-polypyrrole (Au-PPy) nanocomposite-coated silica, is described for the efficient solid-phase extraction (SPE) of six common microcystins (MCs) well below the recommended United States EPA and World Health Organization (WHO) guidelines. With the optimized SPE protocol, samples spiked with MCs were determined at ng/L concentrations by liquid chromatography-mass spectrometry (LC–MS) in different aqueous sample matrices, including HPLC-grade, tap, and lake wat...
