dc.description.abstractNanocomposites and in particular polymer nanocomposites play a significant role in adsorption treatment of wastewaters. The use of nanobifillers in polymer nanocomposites is relatively less explored area in materials science. Graphene oxide (GO) and its nanocomposites have drawn increasing interests in the application of water treatment, especially for the removal of metal-containing pollutants. GO has large surface area, due to its sheet-like structure. Recently, GO and clay minerals like bentonite (montmorillonite) find an application as adsorbents because of their good adsorption capacity and low cost. GO nano-sheets were synthesized using a modified Hummers’ method from graphite powder. A natural bentonite from Bulgaria deposit was activated and organically modified by using octadecylamine (ODA) to obtain organobentonite (OB). Nanocomposites based on organobentonite and graphene oxide (OB: GO = 10: 1 and OB: GO = 5: 1) were prepared through a facile ultrasonic-assisted method and exhibited excellent synergetic adsorption behavior for methylene blue (MB). The synthesized nanocomposite bifillers were characterized by XRD and FTIR and their adsorption capacities to methylene blue (MB) were determined.
