“…Graphene has been proposed as an absorbent for organic molecules for catalytic and environmental applications [51]. This could especially be important for C 6 H 12 and C 6 H 10 , which are abundant byproducts of petrochemical industries and have both been identified as hazardous to human health [52,53].…”

“…The same phenomenon was reported by Dahane et al, 43 where the most soluble constituent methomyl gave recoveries in the range of 43-60%, compared to less soluble pesticides such as diazinon, whose recovery was between 58 and 106%. 47 Poor performance, i.e., recoveries <60.0% for C18 cartridges, have been previously reported.…”

Carbon nanotubes (CNTs) have demonstrated outstanding chemical and mechanical stability, electrical properties, and strong interactions with aromatic compounds owing to the p-electron system on the graphene sheets. Taking advantage of these unique properties, we have developed a fully validated sample pre-concentration technique for determination of polychlorinated biphenyls (PCBs) in aqueous environments using gas chromatography combined with a micro-cell electron capture detector (GC-mECD). The optimized method using pristine MWCNTs gave recoveries in the range of 46.0-92.5%, 51.4-91.5%, 48.7-77.8% for tap water, river water, and lake water, respectively. Compared to conventional C18 adsorbent and oxidized MWCNTs (oMWCNTs), pristine MWCNTs provided the best recoveries, thereby confirming that MWCNTs are excellent alternatives for C18, with the ability to achieve high performance. The developed protocol achieved method detection limits in the range of 0.002-0.011 mg L À1 and relative standard deviation (RSD) < 15.5%.

“…This trend was also reported for sorption of PAHs on carbon nanotubes and multiwalled carbon nanotubes. 44 On the other hand, although the isothermal adsorption tests using individual PAHs ( Figure 6C) showed a significant q e value for NAP, the low removal capacity observed in the PAHs mixture could account for the competition among the PAHs for the active sites on the surface of MC3py550. Moreover, a clear trend of the removal capacity with the PAHs hydrophobicity (K ow ) was also observed (Figure 7).…”

Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/ maghemite and/or metallic Fe), have been investigated to be used in magnetically guided water remediation processes from polycyclic aromatic hydrocarbons (PAHs). Chitosan-derived magnet-sensitive materials were first obtained by a one-step coprecipitation method, and then two carbon-derived magnetic chitosan materials were obtained under N 2 gas flow at 550 and 800°C, respectively. The obtained materials were investigated by means of X-ray diffraction (XRD), FTIR spectroscopy, scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), magnetic force microscopy (MFM), and magnetization measurements. Thermal treatment conditions, along with the amounts of chitosan used in the synthesis processes, played a critical role in the crystal structure and magnetic properties of the obtained nanomaterials. The adsorption capacity of chitosan-derived magnet-sensitive materials was tested toward PAHs. The results indicate high sorption capacity for anthracene and naphthalene onto the chitosan-derived material pyrolyzed at 550°C. Furthermore, experiments performed with a mixture of eight PAHs show that PAH molecules with higher hydrophobicity and more extended aromaticity had stronger sorption capacity. Interestingly, due to the obtained results, the use of chitosan is encouraged as a platform for the creation of green adsorbents for further developments in wastewater purification treatments.
