Abstract
Abstract In this work, dithiocarbamate-functionalized graphene oxide (GO-DTC) has been synthesized and applied in removal of cationic dyes; Basic Blue 41 (BB41) and Basic Red 46 (BR46). Morphology and chemical structure of the prepared GO-DTC were studied by SEM and FTIR analyses. Dye removal from wastewater solutions with variable concentration of dyes, pH, and GO-DTC dosage was evaluated. The experiments suggested a pseudo-second order kinetic model for dye adsorption onto GO-DTC, while dye adsorption isotherm data were found to fit Langmuir model. The adsorption efficiency of synthesized GO-DTC towards BB41 and BR46 was calculated to be 128.5 and 111 mg/g, respectively.
