Baohua Gu, a member of the senior research staff at Oak Ridge National Laboratory (ORNL) will be delivering a lecture as part of the Environmental and Water Research Program in the Department of Civil Engineering at Auburn University. His lecture, "Highly-Selective and Regenerable Ion Exchange for Perchlorate Remediation, Recovery and Environmental Forensics," will be held Wednesday, January 24 at 3 p.m. in Aerospace 355. The university community is invited to attend.

Perchlorate has recently emerged as a widespread contaminant found in drinking water and groundwater supplies in the United States and is known to disrupt thyroid function by inhibiting iodide uptake. Among various treatment technologies, the highly-selective and regenerable ion-exchange technology has recently been developed at ORNL for removing perchlorate from contaminated water. Gu's lecture will give a comprehensive overview of the ORNL's work in the development and employment of these technologies.

Gu is leader of the Environmental Chemistry and Technology Group in the Environmental Sciences Division at ORNL. He has more than 20 years of experience in environmental research and development and is the winner of the 2004 R&D 100 Award related to the development of highly-selective, regenerable ion exchange technology for treatment of perchlorate-contaminated water. He has over 100 peer-reviewed journal publications and a recently edited book on "Perchlorate - Environmental Occurrence, Interactions and Treatment". His research interests include biogeochemical transformation, transport, and remediation of environmental contaminants, nanomaterials synthesis and surface enhanced Raman spectroscopy in environmental and biological applications.
