Dispersion of Graphene Using cetyltrimethylammonium bromide (CTAB): Dye Removal and Characterization Studies

The aim of this study to determine the usability CTAB-RGO composites in removal MB from aqueous solutions and investigate stability dispersions. And also, we compared effects three different CTAB concentrations on decolorization MB. performed increasing activity, decreasing average particle size resulting individual graphene layers with concentration. CTAB-RG0 40 80 mg/L were unstable, RGO 120 had good solutions. Effective repulsive forces CTAB-RGO-120 composite prevented forming aggregates. highest rate at neutral pH can result both electrostatic interaction π-π interaction.
