Continuous fixed bed adsorption of C.I. Acid Blue 92 by exfoliated graphite: An experimental and modeling study

► Exfoliated graphite was used for C.I. Acid Blue 92 removal from its aqueous solution. ► EG was able to adsorb the dye with maximum removal efficiency of 96%. ► Langmuir and Radke-Prausnitz isotherms could predict the adsorption behavior of EG. ► Adsorption capacity obtained from Langmuir isotherm was relatively low. ► The continuous system was successfully modeled using LDF mass transfer resistance.
