Development of a portable low-cost voltammetric device to enhance in situ water quality analysis of organic compounds

Nowadays public authorities are looking for ways to acquire real-time water quality for more informative parameters than pH, conductivity, and temperature. So, the goal of this study was to develop a portable voltammetric device to enable in situ water quality analysis of organic compounds. First of all, a literature review was carried out, followed by electronic design, prototyping, and laboratory tests. The system consisted of a potentiostat using a nickel screen printed electrode as a sensor for measuring glucose. The prototype was tested and showed promising results in terms of detecting variations in the concentrations of the target parameter.
