Design and Development of a New Hybrid Spectroelectrochemical Sensor; Spectroelectrochemical Sensor for Technetium Applicable to the Vadose Zone

The general objective is the design and implementation of a new sensor technology that offers the unprecedented levels of specificity needed for analysis of the complex chemical mixtures found at DOE sites nationwide. The specific objectives are threefold: demonstration of the general sensor concept on a variety of model systems; development of a sensor for ferrocyanide with testing on waste tank simulant; and development of a sensor for pertechnetate applicable to the Vadose Zone
