In this study, MnO4- ions are adsorbed onto GO/PVA/Fe3O4 composite. Results showed that after 18 hours, the adsorption process gets equilibrium with the adsorption capacity is 187.8 mg.g-1, the mass of adsorbent is 0.005 g in 10 mL of 200 mg.L-1 MnO4- ions solution. The influence of temperature was also investigated and with the increasing of temperature, the adsorption capacity also increases, so the adsorption is endothermic. The sorption process obeys pseudo-first-order kinetic.
