Demonstration and Validation of a Portable Raman Sensor for in-situ Detection and Monitoring of Perchlorate (ClO4-)

Abstract

The overall goal of the project was to field-demonstrate, validate, and optimize the performance and sensitivity of a portable Raman sensor for rapid detection and analysis of the energetic compound perchlorate (ClO4-) in contaminated groundwater at multiple U.S. Department of Defense (DoD) military installations. Specific objectives were to: (1) construct and validate the performance of a portable Raman sensor forClO4- detection in groundwater with varying characteristics, (2) optimize the performance and sensitivity of the sensor through nano-fabrication of surface-enhanced Raman scattering (SERS) substrates and the fiber-optic sensor probe, (3) optimize field-testing methodologies and establish testing protocols, (4) partner with a commercial vendor for large-scale production of SERS substrates via Nano imprinting, and (5) evaluate and document the cost effectiveness of the new sensing technology by comparing with conventional laboratory-based analytical protocols.
