In this study, tetraethylenepentamine modified magnetic graphene oxide nanomaterial (TMGO) was prepared and characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and vibration sample magnetometer (VSM). All the characterizations proved that the modification and preparation of TMGO were successful. The TMGO nanomaterial was used in the adsorption of Acid Red 18 (AR) in aqueous solution. The parameters like pH of solution, adsorption kinetics and isotherms were all investigated. The results indicated that the TMGO nanomaterial had satisfied adsorption ability and the maximum adsorption capacity was 524.2 mg g -1 at 45 °C and pH 6. The adsorption capacity remained at 91.8% of the initial value after five cycles. The adsorption process with AR was found through fitting the pseudo-second-order kinetics equations and the Freundlich adsorption model. The experimental results demonstrated that the TMGO nanomaterial could be rapidly extracted from the medium and had a good adsorption ability to remove dyes in wastewater.Keywords: adsorption, dye, graphene oxide, magnetic nanoparticles, tetraethylenepentamine IntroductionIncreasing interests were focused on the environmental health, especially the removal of toxic organic or inorganic pollutants from water because of the water pollution during the development of modern industry.1 Among the various toxic pollutants, dye was one of the most serious problems because of the visible color, complex component and low biodegradability.2 Dye was widely used in direct textiles, printing and dyeing. It showed many damages to plants, animals and human beings.3 Therefore, wastewater containing dyes should be treated adequately before being discharged. 4 The development of materials for removal of dyes exhibited considerable importance.Recently, many kinds of materials and nanomaterials such as silica nanoparticles, carbon nanotube, gold nanoparticles and metal oxide nanoparticles were utilized as adsorbents for removal of toxic compounds. [5][6][7][8] Graphene oxide (GO) attracted significant interests due to its high mechanical strength and facile functionalization ability.9 It could be a good material for adsorption owing to the large specific surface area, abundant oxygen containing groups and high water solubility.10-12 Magnetic nanoparticles (MN) were also good in separation of toxic dyes by simply using an ordinary magnet. 13,14 After the combination of MN and GO, magnetic GO (MGO) and related complex nanomaterials were prepared and used in pollution control and sensors were benefited from the advantages of both During the various kinds of applications, many advantages of MGO were demonstrated including high adsorption capacity, easy recycling and improved stability.In this study, tetraethylenepentamine was used in the modification of Fe 3 O 4 magnetic nanoparticle (TMN) Tang et al. 335 Vol. 29, No. 2, 2018 to increase amino group...

Magnetic graphene composites (MGCs), which are composed of magnetic nanoparticles with graphene or its derivatives, played an important role in sensors development. Due to the enhanced electronic properties and the synergistic effect of magnetic nanomaterials and graphene, MGCs could be used to realize more efficient sensors such as chemical, biological, and electronic sensors, compared to their single component alone. In this review, we first reviewed the various routes for MGCs preparation. Then, sensors based on MGCs were discussed in different groups, including optical sensors, electrochemical sensors, and others. At the end of the paper, the challenges and opportunities for MGCs in sensors implementation are also discussed.
