Graphene oxide (GO) was synthesized via a simple electrochemical exfoliation of graphite in a surfactant-containing aqueous solution. A novel custom-made surfactant, 1,4-bis (neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulfonate (TC14) was used to assist the exfoliation process. The structural and magnetic properties of prepared GO were examined using electron microscopies, micro-Raman, and Fourier transform infrared spectroscopies, and vibrating sample magnetometer (VSM). Room temperature VSM measurement showed a diamagnetic response of pristine GO under a high magnetic field. This indicated the low defect and the absence of any impurities in the synthesized GO. Simple mixing of GO and carbon nanotubes (CNTs) was also done to study their magnetic properties. CNTs were initially synthesized from waste engine oil using thermal chemical vapour deposition. It was found that the addition of magnetic CNTs has successfully induced the ferromagnetism in the GO sample. The saturation magnetization and average coercivity of GO/CNTs were observed to be 6.13 memu and 345.12 G, respectively. This study offers a low cost and simple method to induced magnetism in GO as compared to the common chemical modifications of GO.

“…Among the sorbents used, magnetic graphene or carbon nanotubes have attracted much attention due to their large surface areas (>2000 m 2 /g for graphene and carbon nanotubes), and π–π electrostatic stacking property, which provides strong interactions with aromatic compounds . Up to now, magnetic graphene and magnetic carbon nanotubes have been successfully employed as adsorbent materials in various environmental analysis . The combination of magnetic graphene and carbon nanotubes nanocomposites, which formed a “3‐D” open structured material, has been utilized for enrichment and detection of small organic molecules .…”

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.

“…As a low‐polarity material, graphene is incompetent to polar and organic sample extraction in the aqueous phase . Therefore, chemically modified graphene (such as amine , polydopamine , nitro‐substituted tris(indolyl)methane , and benzylamine‐modified ) have been extensively studied because of their excellent properties in environmental pollutant removal and enrichment procedure . However, amine‐based graphene were limited by pH of modifier.…”

A green and novel deep eutectic solvent modified graphene was prepared and used as a neutral adsorbent for the rapid determination of sulfamerazine in a river water sample by pipette-tip solid-phase extraction. Compared with conventional graphene, deep eutectic solvent modified graphene can change the surface of graphene with wrinkled structure and higher selective extraction ability. The properties of deep eutectic solvent modified graphene and graphene were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Static adsorption showed deep eutectic solvent modified graphene had a higher adsorption ability (18.62 mg/g) than graphene. Under the optimum conditions, factors such as kinds of washing solvents and elution solvents and volume of elution solvent were evaluated. The limits of detection and quantification were 0.01 and 0.03 μg/mL, respectively. The method recoveries of sulfamerazine were in the range of 91.01-96.82% with associated intraday relative standard deviations ranging from 1.63 to 3.46% and interday relative standard deviations ranging from 0.68 to 3.84%. Deep eutectic solvent modified graphene showed satisfactory results (recovery was 95.38%) and potential for rapid purification of sulfamerazine in river water sample in combination with the pipette-tip solid-phase extraction method.
