Regeneration of Activated Carbon Using Photo-Oxidation Process

Article Preview

Abstract:

Activated carbon has been used as an adsorbent for centuries. For purpose of regeneration, advanced oxidation processes is sugested, this approcah could be viable from the econmic and environmental point of view, and appears as an alternative to the many of inefficient single-step processes actaully applied for the regeneration process. The results showed that the Titanium dioxide can easily regenerate the AC by oxidizing the organic compounds adsorbed on the surface of AC. The increase of UV light intensity has a positive effect on the adsorption capacity. However, the increase of TiO2 concentrations have a small negative effect on the adsorption capacity of the AC. Keywords: regeneration, activated carbon, photo-catalyst
