Abstract

This paper showcases the design and development of a portable sensing system that could be used in-situ to detect the concentrations of nitrate salts present in the groundwater. Electrochemical Impedance Spectroscopy was employed to identify and display nitrate concentrations by using planar interdigital sensor immersed in the stream water samples. Calibration samples were prepared by serial dilution of the nitrate stock solution in the laboratory and test samples were collected from different surface water sources. The test samples were evaluated by the commercial equipment and designed system. Although a difference was observed between these two results, the designed system showed a good linear relationship between the measured nitrate concentrations (range from 0.1 to 0.5 mg/L) of the water solution in the real part of the impedance. The promising comparative results announced the extraordinary potential of the developed system for its in-situ nitrate contamination detection with real-time monitoring.
