The possibility of the application of a potentiometric sensor with all-solid-state electrodes for the quality control of different natural waters
Abstract
The quality of various natural waters was examined by a new potentiometric sensor with six all solid state electrodes containing an appropriate lipophilic compound in a polymer membrane. Physicochemical parameters such as conductivity and acidity of tested waters were also tested. All waters were neutral or slightly alkaline and contained different ions (e.g., Cl–) due to the place of their sampling (a coastal zone and a moraine plateau). They differed significantly in conductivity values. The results obtained by potentiometric sensor, elaborated by chemometric methods showed that tested waters (surface, subsurface, mix subsurface, mix groundwater, rain, and tap) could be grouped in terms of their conductivity values. It means that this sensor is capable of discriminating between waters of low, middle, and high conductivity and may be a good tool for the quality analysis of natural waters.
