Destroy NAPL with Fenton’s Reaction / Catalyzed Hydrogen Peroxide Oxidation

Chemical oxidation using Fenton’s reaction or CHP involves free radical generation and direct oxidation when hydrogen peroxide is combined with a metal (iron) catalyst. Ferrous salts or iron chelates are commonly used as catalysts. In some cases, naturally occurring iron in the soil may be used to catalyze the peroxide.

Advantages of using CHP include its high oxidation potential (2.7-2.8 electron volts), rapid reaction with efficiency in a short time frame, usefulness in destruction of NAPL, remediation of a wide variety of hydrocarbon compounds, and low-cost potential. The primary limitation of CHP is limited contaminant contact and reduced radius of treatment often caused by rapid decomposition.
