Characterization of Iron Oxides at Surfaces for Drinking Water Biofilm Studies
EMSL Project ID
2099
Abstract
The work requested is to complement research underway at Montana State University. The title of the current project is Interactions Among Factors That Influence Biofilm, Bacterial Regrowth, and Corrosion in Distribution Systems. The PI for this project is Dr. Anne Camper and the Project Manager is Dr. Phillip Butterfield. I am a research engineer working with Dr. Butterfield. This project consists of studying the interactions among biofilms, humic substances, and iron oxides under a variety of conditions in simulated drinking water pipes. The work requested is characterization of the two sources of iron oxides used. The first source is scrapings from aged iron pipes recently replaced in the vicinity of Boston, MA. The second source is a synthetic iron oxide deposited on 0.5-mm glass beads. Efforts to characterize the oxide coating on these beads using XPS here at MSU have been inconclusive. More definite results should be available using DXRD, FTIR, Mossbauer Spectroscopy or a combination of these. Characterization of the oxide coating on the glass beads may be possible in-situ, or it may require removal of sufficient coating from the beads.
