Paper Title:
Different Ways to Regenerate an Activated Carbon: Comparison between an Activated Carbon from Cork and a Commercial Carbon
  Abstract

Activated carbons are materials extensively used to remove a variety of pollutants in different media. The porous structure, the surface chemistry and the type of adsorptive determine the potential of activated carbons as an adsorbent material. However, in a more global perspective it is necessary to consider other factors such as the economical viability of production and reuse. This last factor depends on the capacity of regeneration of the activated carbons after each application. Following this guideline, the objective of this work was to evaluate the capacity of regeneration of some specific activated carbons prepared from cork oak wastes, used in the adsorption of phenolic compounds in the liquid phase. Simultaneously, the performance of our carbons are compared with the behaviour of a commercial carbon (Norit SX plus). The experimental procedure consists in the adsorption of one phenolic compound, followed by the regeneration of the adsorbent, succeeding a series of adsorption/regeneration processes. The methods of regeneration used were simple washing with distilled water under magnetic stirring, washing with ultrasound and thermal regeneration under inert atmosphere. The performance of the activated carbons was strongly dependent on their nature and the regeneration method applied.
