Portable Sensor for Rapid In Situ Measurement of Trace Toxic Metals in Water

Completed Technology Project

Project Description

Portable Sensor for Rapid In Situ Measurement of Trace Toxic Metals in Water Project Image
Development of a sensor to detect select trace toxic heavy metals (Ag, Cd, Mn, Ni, and Zn) in water is proposed. Using an automatic side-stream sampling technique, this compact, electrochemical sensor will use small volumes of water and detect metals in the low parts-per-billion range. The novel coupling of a high-performance novel electrode material, microarray electrode geometry, and a highly sensitive sensing algorithm allows for a sensor with low detection limits and excellent specificity. Additionally, the sensor will show long-term repeatability and reliability, while requiring minimal maintenance or user calibration time. The sensor and its components have been engineered to function in a microgravity environment and for easy integration with the Water Recovery System. Giner will partner Johnson Space Center to ensure the ability of the sensor to detect trace metals in a range of reclaimed water samples and determine the appropriate concentrations. This sensor will detect trace heavy metals in water in near real-time, allowing for timely response and resolution to water contamination problems. More »
