Adsorption capacities of reduced graphene oxide using urea as a reductant
Abstract
In this work, graphene oxide was reduced at low temperature using urea as reductant. The obtained reduced graphene oxide was characterized by Fourier transform infrared spectroscopy, Brunauer- Emmett- Teller (BET) surface area measurements, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy and LECO combustion analysis. Bath adsorption experiments onto methylene blue were carried out to study the effect of adsorbents based on adsorbent dosage, pH solution and contact time parameters. Graphene oxide reduced by urea in this work shows a higher adsorption capacities comparing with using commercial activated carbon. The adsorption capacities of both adsorbents were fully agreed with their specific surface areas and the degree of restoration of π-conjugation parameters.
