Groundwater Technology Development

Overview Oxidative and Reductive In-Situ TCE Destruction

Destruction of TCE Using Oxidative and Reductive Pathways as Potential In-Situ Treatments for the Contaminated Paducah Groundwater" was presented as a KRCEE quarterly report to introduce the development of Chemical and Materials Engineering projects related to oxidative and reductive in-situ trichloroethene (TCE) destruction. 

Project Title

Destruction of TCE Using Oxidative and Reductive Pathways as Potential In-Situ Treatments for

Contaminated Paducah Groundwater

Project Summary

When considering reductive technologies for groundwater remediation, it is important to understand the underlying principles that govern kinetics of zero-valent metal dechlorination. Studies involving the use of nano-scale metals (characteristic length <100nm) for chloro-organic degradation have increased reaction rates by 1-2 orders of magnitude with minimal intermediate formation. Typically, these metals are synthesized using modifications of the aqueous phase reduction of metal ions using sodium borohydride presented by Glavee and coworkers. The use of a bimetallic system increases the reactivity of the particle surface by incorporating a second metal that can typically act as a hydrogenation promoter.
