Abstract
This study addresses the pressing issue of monitoring the ionic composition of aqueous media, which is of significant importance for the energy sector. Particular attention is paid to the development of new ionophores, environmentally friendly plasticizers, miniaturization technologies, and methods for increasing the service life of sensors. In the experimental portion of the study, a laboratory conductivity meter based on a unique cell manufactured using 3D printing was developed and tested. A comparative evaluation of electrodes made of various materials was conducted: copper, graphite and composite polymers with added graphite powder. The results showed that copper electrodes provide high measurement accuracy, while graphite electrodes exhibit overestimated readings at low concentrations due to their surface properties. This study confirms the effectiveness of the proposed approach and forms the basis for further research into the development of optimized electrode materials for ion-selective elecrodes.
