Numerous commercial operations and the Department of Energy¿s environmental management program seek reliable waste remediation and pollution prevention systems. This is creating a strong demand for sensors that can reliably monitor, in real time, the efficacy of remediation processes and pollution prevention measures. Conventional analytical instruments for heavy metals are expensive and complex (such as AAS, ICP and X-ray based analysis) and they generally require time consuming sample handling and operator intervention. This project seeks to develop a new analytical device based upon the integration of photocatalysis, internal reflection spectroscopy and optical fiber technology. In Phase I, the proof-of-concept of such a sensor will be demonstrated by using photocatalytically active optical fibers for the detection and analysis of mercury, cadmium and chromium. Sensors will be fabricated and evaluated to determine their performance. Phase II will optimize the design, build prototypes and field test the technology.

Commercial Applications and Other Benefits as described by the awardee: Novel sensors to be developed during this program will serve the industrial and municipal need for continuous, optimal and reliable monitoring and operation of chemical and environmental remediation processes. The DOE¿s Environmental Management program will benefit in its effort to cost effectively, reliably, and completely clean up heavy metal contaminants.
