The separation performance of these membranes for thiophenic sulfurs from n-hexane was evaluated. The competitive adsorption of thiophenic sulfurs on these membranes was investigated by varying the loaded ions, the ion concentration and the activation temperature. The regeneration of used membranes was also investigated.
