“…Similarly, fine continuous nanofibers of polystyrene were spun by combining DMF:THF (4:1). The study has shown that the higher conductivity of DMF and volatility of THF favored the formation of smooth nanofibers (Uyar and Besenbacher 2008;Uyar et al 2009;Xu et al 2010a;Xu et al 2010b).…”

“…There is also the possibility of hydrogen bonding between the amide group of nylon 6 and the -OH group on the surface of the analyte with any of the two acting as hydrogen bonding donor. Moreover, the role of the strong hydrophobic interaction between the π-electrons of the methylene groups of nylon 6 and the π-electrons of the poly aromatic hyroxypyrene cannot be overemphasized (Kloskowski et al 2009;Xu et al 2010a;Xu et al 2010b). More so, the aromatic rings of the matrix network on SDVB permits the electron-donor interactions between the sorbent and the bonds of the aromatic analyte.…”

“…This means that the contact time is an important parameter in selecting a suitable sorbent. Sorbent with higher hydrophilic functional groups would be expected to adsorb the analyte faster due to more effective sorbent-analyte interaction resulting from increase in mass transfer (Xu et al 2010a;Xu et al 2010b;Qi et al 2008;Bagheri et al 2012). This suggests that the hydrophilic functional groups like amide and carboxylic groups on some of the sorbents did contribute greatly to the rapid sorption of 1-hydroxypyrene.…”

“…Until now, various pretreatment techniques have been attempted to extract PAEs from aqueous samples, such as, solid-phase microextraction (SPME), 9,10 dispersive solid-phase extraction (DSPE), 11,12 liquid-liquid extraction (LLE) 13 dispersive liquid-liquid microextraction (DLLME) 14,15 and solid phase extraction (SPE). 16,17 However, the¯bers used in SPME are relatively expensive. 18 Adsorbent of DSPE is hard to recycle.…”

We report a novel solid-phase extraction adsorbent for the preconcentration of three phthalate esters (PAEs) from aqueous samples. The material was obtained by modifying multiwalled carbon nanotubes (MWCNTs) with mesoporous silica. The structural characterization of the adsorbent was conducted by Fourier transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM) and N 2 adsorption-desorption measurement, which con¯rmed the successful coating of mesoporous silica on MWCNTs and the adsorbent possessing large surface and porous structure. The e®ects of adsorbent amount, type and volume of eluent and sample pH on extraction e±ciency were optimized. Following extraction, the PAEs were quanti¯ed by high performance liquid chromatography (HPLC). Under optimal conditions, the recoveries ranged from 89.8% to 96.3%. The calibration plot was linear in the 3-1000 ngÁmL À1 concentration range, with correlation coe±cients ranging from 0.9993 to 0.9995. The repeatability of the method, expressed as relative standard deviation (RSD), ranged from 3.8% to 7.7% (for n ¼ 5). Limits of detection (LODs) were between 0.28 ng mL À1 and 0.53 ngÁmL À1 . The relative recoveries (RR) for spiked river water, pond water and tap water samples were in the ranges of 80.9-98.0%, 82.7-96.1% and 88.3-95.5%, respectively. The results showed that the method obviously had a large potential for preconcentration and determination of PAEs in environmental samples.
