In this study, cocoa pod husk (CPH) was used as adsorbent for removing methylene blue (MB) from aqueous solutions. Before the adsorption studies, the CPH was treated using sodium hydroxide (NaOH) to increase its adsorption capacity toward methylene blue (MB). The NaOH-treated CPH was characterized b...
