Abstract: A method of preparing an activated charcoal can include obtaining palm leaves; grinding the palm leaves; refluxing the ground palm leaves with sodium hydroxide (NaOH) to obtain a basic solution; draining the basic solution from the palm leaves; washing and drying the ground palm leaves; refluxing the dried ground palm leaves with potassium permanganate (KMnO4) to obtain a reaction mixture; heating the reaction mixture; washing the reaction mixture with hydrochloric acid (HCl); and drying the reaction mixture to obtain activated carbon. A method of removing a pollutant from an aqueous solution includes contacting the activated carbon as prepared in with the aqueous solution to remove organic dyes.
