Annotation
This study presents the development of an ion-selective membrane for the determination of cobalt ions in multicomponent complex mixtures. The optimal composition of the membrane components, their ratio, and the optimum conditions for the synthesis process were established. The composition and structural characteristics of the synthesized materials were investigated using modern analytical techniques. The developed ion-selective membrane is intended for use in an ion-selective electrode for the selective determination of cobalt ions in complex multicomponent mixtures.
