Abstract

In situ chemical oxidation (ISCO) is a technique used to remediate contaminated soil and groundwater systems. In this study superoxide oxidations of chlorinated solvents, PAHs, PCHs, PCBs, diesel and petroleum products were investigated in soil slurry systems under a variety of experimental conditions. Superoxide, generated from hydrogen peroxide and sodium hydroxide, functions as a super nucleophile and strong oxidizing agent, which rapidly reacts with different organic pollutants and swiftly mineralizes them to sodium carbonate.
