Description:

Objective:

The overall aim of this project was to develop a better fundamental understanding of important physical-chemical processes and abiotic factors which may affect the kinetics of hydrogen peroxide decomposition as well as oxidation of organics in the subsurface environment.

Approach:

In this research, extensive work was conducted using systems containing iron oxides as model reactive soil and aquifer materials because of their central importance as components, and because evidence indicates that they are potentially important catalysts in these environments. Another focus was on modeling the effect of phosphate, which is commonly used to retard the rate of hydrogen peroxide decay. Its mode of action, however, has not been well established. Hydrogen peroxide decay kinetics was also studied in the presence of collected authentic aquifer material with and without treatment to remove oxides as a way of establishing relationships between surface chemistry and rates of hydrogen peroxide loss. Extensive studies were conducted with several organic compounds to determine the potential for surface catalyzed oxidation and to provide information upon which to develop a conceptual and a mathematical model of the reaction mechanism. Lastly, work was conducted on the use of hydrogen peroxide to treat a soil contaminated with pentachlorophenol.

Expected Results:

It is expected that this study will show that hydrogen peroxide alone can be as effective as Fenton's reagent (a mixture of ferrous iron and hydrogen peroxide) in treatment to remove pentachlorophenol.
