Characterization of various drinking waters by new potentiometric taste sensor with lipid, lipid-like polymer membranes

A new sensing system comprising five all-solid-state electrodes with lipid, lipid like-polymer membranes was applied for rapid qualitative and quantitative analysis of various drinking waters. The results elaborated by chemometric methods revealed sensitivity to CO2 content in drinking water, suggesting that this sensing system could be used as a taste sensor. The ability of taste sensor to perform quantitative analysis of minerals content (Ca2+, Na+ , Mg2+, K+ , F– , Cl– , HCO3 – , SiO2 ) concentration in water was also demonstrated. The developed sensing system seems to be promising solution for the analysis of treated drinking water.
