In this research, a systematic study of the adsorption and decolorization process of reactive
red 198 (RR198) onto Fe3O4-graphene oxide (Fe3O4-GO) was applied via various pH,
sorption time and temperature. Investigation of reactive red 198 adsorption kinetics were
satisfied by the pseudo-first and second order model. According to the kinetic examinations,
the equilibrium reached within 15 min following the pseudo-second-order model. The
sorption data have interpreted by the Langmuir model with the maximum adsorption of …
