A Microelectronic tongue employing Boron-Doped Diamond fim microcell for quantitative analysis of French wastewaters

In this study, we developed an electronic tongue for the simultaneous detection and identification of six heavy metals in Rhône water (Lyon) using a new electrochemical microcell based, on Boron Doped Diamond (BDD), using Anodic Stripping Voltammetry (DPASV). First, we prepared the synthetic water solutions containing Zn, Cd, Cu, Ni, Pb and Hg, then applied the measuring methods and the data analysis to the analysis of real Rhone water. The results of the Principal Component Analysis (PCA) showed that all present metals are properly identified.
