Rutgers CAIT personnel recently developed a real-time lead sensor for use in sediment systems. The largest hurdle by far however was the development of a digestion procedure to accurately assess the actual concentration within a given mass of sediment. The sensor that was developed can only measure lead in the dissolved phase, as a result in order to deploy this sensor system a digestion step similar to those used in standard laboratory analyses had to be developed. Standard digestion procedures involve extended periods of time and high doses of acid which could damage our sensor system. As a result, an accelerated enzyme digestion procedure was identified and customized for this application. The procedure was tested and applied to field collected sediment sample and results were compared to standard laboratory procedures (Atomic Adsorption). Results indicate that the accelerated enzyme digestion procedure was successful and gave results that were comparable to the standard laboratory results.
In this project, we developed a novel, integrated on-chip sample-to-answer platform capable of detecting lead ions (Pb +2 ) directly in sediment sampl...
The goal of phase I of this project was to provide a novel technology capable of assessment of sediment contamination in New York harbor. NY harbor is...
