Batch adsorption experiments were performed using 40 mL glass vials equipped with polytetrafluoroethylene-lined screw
caps. Vials received 20 mg of adsorbent and a full volume of background solution containing 0.02 M NaCl , followed by organic
solute in a methanol carrier (2-naphthalenesulfonate in distilled water) that was kept below 0.1% (v/v) to minimize possible
cosolvent effects on adsorption. The pH of aqueous solution was adjusted with 0.01 M HCl and 0.01 M NaOH. The samples were
covered with aluminum foil from light and were mixed end-overend at room temperature for 24 h. This period of time was sufficient
enough to reach apparent adsorption equilibrium (no further uptake) based on kinetic measurements.
