Ionic liquids (ILs) have been efficiently used as a "designer sorbent" in sample preparation. A novel 1-(3-aminopropyl)-3-(4-vinylbenzyl)imidazolium 4-styrenesulfonate IL monomer was synthesized and copolymerized with 1,6-di(3-vinylimidazolium) hexane bishexafluorophosphate IL as cross-linking agent to prepare a cross-linked polymeric ionic liquids (PILs) monolith. Coupled to high-performance liquid chromatography (HPLC), the PILs monolith was used as a solid-phase microextraction (SPME) sorbent to extract some polar endocrine disrupting chemical (EDCs) such as estrogens, bisphenol A, and phthalate esters in aqueous samples. Preparation and extraction conditions were investigated and optimized to obtain satisfactory extraction efficiency. Limits of detection (LODs) of the proposed method for three steroid estrogens and bisphenol A were 0.25 and 0.2 μg L(-1), respectively, which were lower than or comparable to some other sample preparation methods. Intra- and inter-day repeatability for all the analytes was 2.2-12%. The monolith-to-monolith repeatability was 7.4-15%. The extraction performance of the method for analysis of target estrogens in treated domestic wastewater was investigated and compared with a dispersive liquid-liquid microextraction (DLLME) method. The proposed SPME method provided better sensitivity and higher resistance to matrix interferences.

“…These biomimetic receptors are of great practical value in various fields, such as sample pretreatment, drug delivery, and biomedical diagnosis [12][13][14][15][16]. In recent years, molecular imprinting has attracted considerable attention as a novel fabrication technology for highly selective adsorbents [17][18]. A common approach to synthesize molecularly imprinted polymers (MIPs) involves arrangement of functional monomers and template molecules prior to polymerization in presence of certain cross-linkers.…”

“…Consequently, various magnetic materials were synthesized to conduct the MMSPD procedure. Magnetic C 18 , carbon nanotubes , silica , molecularly imprinted polymers , graphene , and metal–organic frameworks were all exploited as adsorbents for the convenience of separation after the adsorption step. Both organic pollutants and heavy metals could be concentrated by MMSPD.…”

A vortex-assisted magnetic matrix solid-phase dispersion method was proposed for the determination of polychlorinated biphenyls in different matrix water samples by gas chromatography with electron capture detection. Magnetic bamboo charcoal (MBC) was synthesized for the adsorption of polychlorinated biphenyls in water samples. Complete separation of the liquid phase and the solid magnetic bamboo charcoal was easily achieved by using a permanent magnet. Under the optimized conditions, good linearity in the range of 0.006-5.0 μg/L was obtained with regression coefficients (r) higher than 0.9986. Based on a signal-to-noise ratio of 3, limits of detection were found to be 0.001-0.003 μg/L. Relative standard deviations ranged from 2.92 to 6.56%. Relative recoveries were 96.6-111.2% for the spiked wastewater sample and 90.7-104.7% for the spiked lake water sample. All results showed that the proposed method was simple, sensitive, and reliable for the determination of polychlorinated biphenyls in water samples.
