An Electrode-Matrix Cell for Electrolytic Conductivity Measurements

Preliminary results on the design and investigation of an electrode-matrix cell for electrolytic conductivity measurements are presented. A cell prototype has been conceived with the end of studying the electrical and current field behavior in aqueous solutions with different electrode configurations. The cell has been modeled using the boundary element method in order to obtain suitable cells for electrochemical measurements with computable constant. The calculated cell constants, corresponding to different configurations of the electrodes, were compared with the measured values. Measurements were performed on aqueous solutions with different ion concentrations while varying the supplied electrode configuration.
