The effectiveness of phenol removal from aqueous solution by different adsorbents was experimentally studied. Results revealed that the pH and adsorbent dosage to be the main factors in this adsorption study. It is found that functionalized carbon nanotubes (CNTs) give the highest removal of 88% followed by 82.3% and 82.2% for magnetic biochar and raw CNTs respectively. Adsorption isotherm studies fit the Langmuir model better than the Freaundlich model and adsorption kinetic follows pseudo-second order.
