Advanced electronic tongue concept

This effort, directed at developing a sensor for evaluating water quality, is based on electrochemical techniques that detect and identify ions in solution. This paper discusses the use of Cyclic Voltammetry (CV), corrosion measurements, and Anodic Stripping Voltammetry (ASV) to measure three marker ions Cu, Fe, and Zn using the electronic tongue concept. The use of genetic algorithms is suggested as an approach to facilitate the search for optimum measurement conditions. In addition, the possibility of changing the physical conditions of the sample chamber is discussed as a way of increasing the sensor´s apparent sensitivity of and confidence in the measurements.
