Methyl Red Dye Adsorption on PMMA/GO and PMMA/GO-Fe3O4 Nanocomposites: Equilibrium Isotherm Studies
Performances of the methyl red (MR) dye adsorption on poly(methyl methacrylate)/graphene oxide (PMMA/GO) and poly(methyl methacrylate)/graphene oxide-Fe3O4 (PMMA/GO-Fe3O4) nano composites as adsorbents were investigated. Our results showed that for adsorption of MR dye on PMMA/GO-Fe3O4 and PMMA/GO nano composites, 80 minutes, 298 K and pH 2 were best contact time, temperature and pH valuefor process, respectively because the optimum adsorption of the MR dye with both nanocomposite adsorbents were observed in these values of the parameters. The equilibrium study results showed that PMMA/GO-Fe3O4 and PMMA/GO were suitable adsorbents for MR dye removing and were best agreement with the Langmuir isotherm model.
