“…Magnetic MIPs can be easily separated from sample solution using an external magnetic field without additional centrifugation or filtration, which simplifies the extraction procedure [32], but the MEKC analysis needs longer time to separate three chlorophenols than our method. The obtained LODs were lower than that of the HPLC [30,31] or comparable to that of the GC [39] methods, except the method of online LVSS coupled with MEKC [32]. Nevertheless, the benefits of MIPs-DSPE-CE method are still obvious, like high sensitivity and selectivity, simple a) y and x stand for the peak area and the concentration (g/L) of all the analytes, respectively.…”

“…As seen, the CE analysis of seven phenols needs shorter time (ß13 min) than HPLC (16-20 min) [30,31], MEKC (ß 35 min) [32] and GC (ß 20 min) [39]. For DSPE procedure, MIPs polymers are completely dispersed in sample solution, which increases the contact opportunity of target analytes and shortens the extraction time.…”

“…Because of the high selectivity and good adsorption capacity of MIPs, they have been extensively utilized as selective SPE sorbent materials [27][28][29]. Recently, several studies have been reported on using MIPs as SPE sorbents for adsorption of phenols [30][31][32]. For example, Lin et al prepared 2,4,6-TCP MIPs by bulk polymerization and applied to SPE for selective preconcentration of phenolic compounds in environmental water samples [31].…”

A simple and sensitive method for the simultaneous determination of seven phenolic compounds in aqueous samples was developed by dispersive solid-phase extraction (DSPE) coupled with capillary electrophoresis (CE), namely phenol, 4-chlorophenol (4-CP), pentachlorophenol (PCP), 2,4,6-trichlorophenol (2,4,6-TCP), 2,4-dichlorophenol (2,4-DCP), 2-chlorophenol (2-CP) and 2,6-dichlorophenol (2,6-DCP). Molecularly imprinted polymers (MIPs) prepared by precipitation polymerization with 2,4,6-trichlorophenol (2,4,6-TCP) as template were used as DSPE sorbents to selectively adsorb the phenols. Various parameters affecting the extraction efficiency were evaluated and excellent CE separation was achieved within 13.5 min by using 15 mmol/L borate buffer containing 15% (v/v) methanol at pH = 9.8. Under the optimized conditions, good linearity was obtained in the range of 2-200 g/L for phenol, 2,4-DCP and 2,6-DCP, 2-300 g/L for 4-CP and 2-CP, 1.5-150 g/L for PCP, and 2-400 g/L for 2,4,6-TCP, with the correlation coefficient (R 2 ) higher than 0.9938. Limits of detection and limits of quantification were in the range of 0.18-0.44 g/L and 0.59-1.45 g/L, respectively. The developed MIPs-DSPE-CE method was also successfully applied to determine the seven phenolic compounds in lake, tap, seawater and tannery wastewater. The average recoveries at three different spiked levels ranged from 70.75 to 106.7% with the relative standard deviations of 1.15-6.28%.

ABSTRACT2,4,6-trichlorophenol molecularly imprinted suspension polymer has been prepared and applied to the molecularly imprinted micro-solid-phase extraction procedure for selective preconcentration of phenolic compounds from environmental water samples. The influence of functional monomer, cross-linker, polymerization condition, porogen, and the ratio of template molecule and functional monomer to cross-linker on the size of the obtained particles were investigated. It was found that methyacrylic acid as functional monomer, divinylbenzene as cross-linker, the molar ratio of template molecule and functional monomer to cross-linker was 1:4:20, the amount of AIBN was 100 mg, ultraviolet radiation at 365 nm were the optimal conditions, and at these conditions, the polymers had the best adsorption efficiency and had the monodispersity of 2 -3 μm microsphere particles. The characteristics of the MIMSPE method were valid by high performance liquid chromatography. This MIMSPE-HPLC method has been successfully applied to the direct preconcentration and determination of phenolic compounds (phenol, 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, pentachlorophenol) in environmental water samples.

“…In recent years, MIPs proved to be useful materials in several areas of analytical chemistry [5,[16][17][18][19][20]. MIPs are synthetic materials with artificially-generated recognition sites able to specifically rebind a target molecule in preference to other closely-related compounds.…”

A B S T R A C TSample preparation is a crucial bottleneck in the whole analytical process. Solid-phase sorbents (SPSs) have aroused increasing interest in research on sample preparation, as they have key roles in obtaining high clean-up and enrichment efficiency in the analysis of trace targets present in complex matrices. The objective of this review is to provide a broad overview of the recent advances and applications of SPSs in sample preparation prior to chromatographic analysis, during the period 2008-13. We include SPSs, such as molecularly-imprinted polymers, carbon nanomaterials, metallic nanoparticles and metal organic frameworks, focusing on solid-phase extraction, solid-phase microextraction, matrix solid-phase dispersion and stir-bar sorptive extraction of typical pollutants in environmental, biological, food and pharmaceutical samples. We propose remaining challenges and future perspectives to improve development of new SPSs and to apply them further.
