NonThermal Method for In Situ Regeneration or Cleaning of Activated Carbon. An alternative chemical method for regeneration of activated carbon at room temperature consisting in the in situ combination of a diluted acid and two oxidants with a catalyst for the desorption and oxidation of pollutants previously adsorbed on carbon material.

20181110The regeneration of GAC was increased with increasing the concentration of NaOH from 0.01 to 0.1 M and decreased afterward. The desorption increased with increasing the ethanol percentage. Using different mixtures of ethanol and NaOH at various concentrations it has been shown that these regenerating mixtures improve the desorption of 4CP.
