Abstract:

This report describes exploratory development of the fiber optic metal ion biosensor initially developed under ONR contract NOOOl4-9l-J-l572. The anticipated application is to monitor wastewater outflows to verify the success of treatment procedures for removing CuII of special interest are wastewater outflows from drydocks resulting from hull blasting and washing operations, which contain ppm levels of Cu and Zn prior to treatment. Issues in this phase of development include the response speed and reversibility of the sensor, transducer stability, and the presence of interferents in treated wastewater. We found that the sensor responded in less than one minute to part per trillion levels of free CuII, that it was reversible at the expected rate, that treated wastewater could be measured, and that the apoprotein was storable for months.
