Abstract
This paper presents the results of an experimental investigation into usage of Fenton’s reagent (a mixture of ferrous salts and hydrogen peroxide) to remediate diesel-impacted soils. A number of process variables such as the presence of iron salts, comparison between ferrous and ferric salts, amount of diesel washed out and mineralized and the use of surfactant to augment the treatment were investigated. Additionally, studies were conducted to evaluate the in-situ injection technique for remediation of diesel-impacted soil using and also its effect on the hydraulic conductivity of the soil. The results indicate that external amendment of iron is not necessary in soils containing iron, and that concentration and volume of were important process variables in modified Fenton’s reaction. The hydraulic conductivity of the soil for was significantly lower than that of water due to generation of gas and other reaction products, which blocked the pores. In some experiments, injection of into the soil matrix met with resistance due to gas generation and the moved up along the sides of the injector.
