Title
Nanoscale And Microscale Iron Emulsions For Treating Dnapl
Abstract
Chlorinated solvents in ground water are most commonly addressed using pump and treat technology. Due to the slow dissolution of solvents from residual or pooled dense non-aqueous phase liquid (DNAPL) sources, pump and treat primarily provides containment, rather than remediation. An innovative technique that can be applied to DNAPL pools located under existing, occupied facilities and the feasibility of using emulsified nanoscale iron particles to enhance dehalogenation of DNAPL free-phase were presented. The emulsified system consisted of a surfactant stabilized oil-in-water emulsion with the nanoscale iron particles contained within the emulsion particles. DNAPL such as trichloroethylene, diffused through the oil membrane of the emulsion particle whereupon they reach the surface of an iron particle where dehalogenation occurs. Reduction of the source mass could significantly reduce plume remediation time and costs. None of the emulsions yielded concentrations of chlorinated by-products in solution above the detection limits. The only product that could be measured was ethylene and some small concentrations of other hydrocarbons. This is an abstract of a paper presented at the 221st ACS National Meeting (San Diego, CA 4/1-5/2001).
