Abstract
In the present study, after synthesizing graphene oxide (with hummer method) and carbon nano tube, were modified by sulfonic groups and characterized by FT-IR and SEM analyses. The batch adsorption experiments were carried out to remove the dye crystal violet from aqueous solution. The effects of pH, adsorbent dose, the initial concentration of analyte and time on the adsorption process were studied. The experimental data were fitted with different kinetic models and isotherms. Also, regeneration and reusability of the synthesized adsorbent has been investigated.
