  • Title: Application of Fenton's reagent to regenerate activated carbon saturated with organochloro compounds.
    Author: Toledo LC, Silva AC, Augusti R, Lago RM.
    Journal: Chemosphere; 2003 Mar; 50(8):1049-54. PubMed ID: 12531711.
    Abstract:
    In this work Fenton's reagent was used to treat activated carbon saturated with organochloro compounds for the oxidation of the adsorbed contaminants and the regeneration of the carbon adsorbent. Activated carbon containing adsorbed chlorinated model substrates such as chlorobenzene, tetrachloroethylene, chloroform or 1,2-dichloropropane was treated with Fenton's reagent at room temperature resulting in a rapid consumption of the organochloro compounds. Thermogravimetric, infrared, BET surface area and MIMS adsorption studies showed that Fenton's treatment has no significant effect on the physico-chemical properties of the activated carbon. The used carbon adsorbents can be efficiently regenerated and recycled with no loss of its adsorption capacity even after five consecutive treatments with Fenton's reagent.
