Development of Sulfate Radical-Based Chemical Oxidation Processes for Groundwater Remediation

Abstract

This study investigates the development of novel sulfate radical-based chemical oxidation processes for treatment of groundwater contaminants. Environmental friendly transition metal species (Fe (II), Fe (III)) have been evaluated for the activation of stable oxidants (peroxymonosulfate and persulfate) for the degradation of model recalcitrant organic contaminants such as polychlorinated biphenyls (PCBs). Sodium citrate, a low molecular weight chelating agent, was tested to control the quantity of iron species in the solution for effective activation of the oxidant.
