Many chlorinated hydrocarbon compounds (CHCs) can be degraded via oxidative or reductive processes.[1] Accordingly, various in-situ chemical oxidation (ISCO) technologies using oxidizing agents such as hydrogen peroxide (Fenton's chemistry), permanganate,[2] ozone or activated persulfate[3], have been developed to remediate impacted environments. Each of these oxidants and their activators offer unique features, and they can be very effective on a varying range of CHCs.
Variations on the ISCO theme such as in-situ stabilization using modified permanganates[4,5] or surfactant-assisted oxidation[6,7] offer potential enhancements for managing known source areas ...
