“…developed a novel method for the extraction and analysis of eight chlorophenols from environmental water samples using graphene‐based SPE, the result showed that the recoveries achieved by using graphene were higher than other adsorbents including graphitic carbon, CNTs and C 18 silica. Shi et al . purified 14 PAHs in mainstream cigarette smoke by a SPE method using GO bound silica as adsorbent.…”

Trans-resveratrol (TRA) has been extensively used in medicine and health products because of its strong biological activity. The solid-phase extraction sorbent for separation of TRA by graphene oxide (GO) is designed. In this study, the interactions between TRA and GO are analysed by first-principles calculations with M06-2X functional at the 6-311 + + G(d,p) level. The adsorption of TRA on GO is stronger than that on graphene, which is attributed to epoxide, hydroxyl and carboxyl functional groups in GO. Interaction analysis shows that hydrogen bonds and p-p interactions exist between TRA and GO surface. The adsorption of TRA depends on the type of oxygen-containing group in GO. Epoxide group in GO is much more attractive for TRA than hydroxyl and carboxyl group. In addition, solvent effects have also been studied, the result shows that the adsorption weakens with the increase of dielectric constant of solvent. The result is significant in the development of solid-phase extraction sorbent for TRA.[a] Dr.

Quinto et al (2014) have developed two different microextraction packed sorbent (MEPS) methods for the analysis of 16 PAHs in real tap water and seawater samples, agricultural irrigation wells, and stream water samples.…”

Porous carbons were prepared by carbonization and activation of phenol formaldehyde resin by gasification with CO at 900 °C. Prepared activated carbon from phenol formaldehyde was characterized by measuring thermogravimetry (TG), differential thermal analysis (DTA), pH, surface area, porosity, and pore size distribution. The specific surface area (SSA) of these carbons ranges from 562 to 1904 m/g, while their point of zero charge (pHPZC) varies from 2.6 to 8.8. The ability of the prepared activated carbon by gasification with CO at 900 °C from phenol formaldehyde resin (PFAC) to remove a series of polycyclic aromatic hydrocarbons (PAHs), e.g., naphthalene, fluorene, phenanthrene, pyrene, and fluoranthene, from mixtures of organic solvents with different polarities and chemical structures was tested. The adsorption capacity increases with the increasing the SSA and pHPZC of the carbons, confirming the roles of dispersive interactions. The kinetics and thermodynamics of the adsorption of phenanthrene as a model compound of PAH on PFAC in the organic solvent were studied. The adsorption capacity became notably greater with an increase in contact time and initial phenanthrene concentration.

“…There are many sample pretreatment techniques for detecting PAHs, such as LLE , dispersive liquid–liquid microextraction (DLLME) , SPE , and SPME . Each of these methods has some limitations: LLE requires large volume of toxic organic solvents and long operation time, and is considered strenuous and not environmentally friendly.…”

A novel adsorbent made of polydopamine-functionalized magnetic graphene and carbon nanotubes hybrid nanocomposite was synthesized and applied to determine 16 priority polycyclic aromatic hydrocarbons by magnetic solid phase extraction in water samples. FTIR spectroscopy, transmission electron microscopy, scanning electron microscopy, and Raman spectroscopy consistently indicate that the synthesized adsorbents are made of core-shell nanoparticles well dispersed on the surface of graphene and carbon nanotubes. The major factors affecting the extraction efficiency, including the pH value of samples, the amount of adsorbent, adsorption time and desorption time, type and volume of desorption solvent, were systematically optimized. Under the optimum extraction conditions, a linear response was obtained for polycyclic aromatic hydrocarbons between concentrations of 10 and 500 ng/L with the correlation coefficients ranging from 0.9958 to 0.9989, and the limits of detection (S/N = 3) were between 0.1 and 3.0 ng/L. Satisfactory results were also obtained when applying these magnetic graphene/carbon nanotubes/polydopamine hybrid nanocomposites to detect polycyclic aromatic hydrocarbons in several environmental aqueous samples.
