Carbon composite electrode for potentiometric determination of silver (I)

The possibilities of carbon composite electrode (CCE) as the sensor for potentiometric determination of Ag(I) were investigated. The conditions for potentiometric titration of silver (reagents, pH, supporting electrolyte and working concentration range) using the sensor have been studied and optimized. The precipitation titration curves were processed by the linearization method. The CCE, in comparison with conventional silver electrode is polyfunctional, and it has a lower cost and better performance
