Abstract Details

2001, PhD, University of Cincinnati, Arts and Sciences : Chemistry.
In recent decades sensors have found a new growth within the scientific community. Their ability to change with the time to the evolving needs of science will help to sustain the advancements to this field of study. They have found a multitude of uses that range from the medical field to industrial sites and even to the nuclear sciences. A common problem associated with many sensors today is their inability to detect the specific analyte in real sample. In many cases, confusion and inaccuracy in test results can occur due to the presence of interferents. Our group has focused on a new type of sensor that will help to improve the selectivity of current sensors. The incorporation of three modes of selectivity into a single device will provide the basis of this increase. By combining already established electrochemical and optical techniques with selective partitioning, an increase in the selectivity was achieved. Once it was realized that this concept had the potential to be highly selective, a natural extension was the detection of specific analytes in an extremely complex sample. In order for this to take place, a new sensor was required. The ability to sample and test at remote locations would enable this sensor to be utilized in testing at the Hanford Nuclear Waste Site in Richland, WA. The samples associated with tank waste located at this site provided an extremely complex sample matrix for the testing of this concept. The focus of this dissertation will be on the design of a portable spectroelectrochemical sensor and the detection of specific analytes in real samples from waste tanks located at the Hanford Site.
