Superfund Research Program
Chloro-Organic Degradation by Polymer Membrane Immobilized Iron-Based Particle Systems
Project Leader: Dibakar Bhattacharyya
Grant Number: P42ES007380
Funding Period: 2000-2019
Project investigators have developed an inexpensive biological technique to make hydrogen peroxide needed for organic dechlorination (using glucose and enzyme) at the site. This allows the use of simple iron salt (with in situ generated hydrogen peroxide) for free radical based destruction of toxic organics from contaminated groundwater in superfund sites. Additionally, this was the first group to develop iron/nickel nanoparticles in membranes for fast detoxification of chlorinated organics at room temperature. These particles are less then 30 nanometers and are highly reactive for organic dechlorination. The researchers were able to convert trichloethylene to nontoxic ethylene using milligram (rather than gram) quantities of nanosized metals.
