Evaluation of BTEX and phenol removal from aqueous solution by multi-solute adsorption onto smectite organoclay

► The removal process of BTEX and phenol was evaluated. ► Smectite clay was converted to organophilic adsorbent by Na2CO3 and HDTMA treatment. ► BTEX were removed from the liquid phase with approximately the same specific rates. ► Phenol was an exception, adsorbing slowly. ► The removal efficiencies in the multicomponent system was: E > X > T > P ≈ B.
