     in this work, preparation of granular activated carbon from oil palm biodiesel solid residue, oil palm shell (psac) by microwave assisted koh activation has been attempted. the physical and chemical properties of psac were characterized using scanning electron microscopy, volumetric adsorption analyzer and elemental analysis. the adsorption behavior was examined by performing batch adsorption experiments using methylene blue as dye model compound. equilibrium data were simulated using the langmuir, freundlich and temkin isotherm models. kinetic modeling was fitted to the pseudo-first-order, pseudo-second-order and elovich kinetic models, while the adsorption mechanism was determined using the intraparticle diffusion and boyd equations. the result was satisfactory fitted to the langmuir isotherm model with a monolayer adsorption capacity of 343.94 mg/g at 30 °c. the findings support the potential of oil palm shell for preparation of high surface area activated carbon by microwave assisted koh activation.
