Characterization and Application of Graphene Oxide based Carbon Composite for Removal of Direct Blue 4

Graphene oxide (GO) sheets exhibit superior adsorption capacity for removing dye pollutants from an aqueous media. In this paper, the facile preparation of GO/ carbon composite as efficient dye adsorbents has been reported. The GO/CC were achieved through sol gel technique. After preparation, the prepared composite was characterized by applying several instrumental techniques, including field emission scanning electron microscopy, BET and determination of pH at the point of zero charge. The effects of the solution pH, contact time, adsorbent dose, the initial dye concentration and temperature on the absorption capacity of GO/CC were investigated.
