Adsorption of Methylene Blue onto Oil Palm (Elaeis guineensis) Leaves: Process Optimization, Isotherm, Kinetics and Thermodynamic Studies

In this study, the potential of oil palm (Elaeis guineensis) leaves (OPL) to remove methylene blue (MB) from aqueous solution was investigated. The adsorption of MB onto OPL was optimized using response surface methodology (RSM) based on a four-variable face-centered central composite design (FCCCD)...
