Extended research on the design and development of a smart nitrate sensor for monitoring nitrate concentration in surface and groundwater are reported in this paper. The developed portable sensing system consists of a planar interdigital sensor, associated electronics, instrumentation, and electrochemical impedance spectroscopy based analysis. The system is capable of measuring nitrate concentrations...
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...
This paper describes the design and development of a sensing system to detect the nitrate concentration by using planar interdigital sensor immersed in the water sample. Water samples were prepared containing two different salts: Sodium Nitrate (NaNO3) and Ammonium Nitrate (NH4NO3) with the concentration ranging from 0.02 PPM to 10 PPM by using the serial dilution method. The water sample was tested...
