ABSTRACT This research aims to make adsorbent from waste bagasse by activation using NaOH, and to study the adsorption equilibrium models and kinetic based on the adsorption of the methylene blue. The adsorption was studied with variation of contact time, adsorbate concentration and adsorption temperature. Waste bagasse was grounded and by size between 80 and 120 mesh and activated with NaOH a…
