Examination the response of potentiometric sensors for chloride and silver ions : bachelor thesis

Cilj ovog završnog rada bio je ispitati odziv potenciometrijskih senzora mjerenjem koncentracije kloridnih i srebrovih iona pri pH=4,00 i pH=4,75 koristeći ion-selektivne membrane. Željeni odziv potenciometrijskog senzora treba pratiti nagib pravca Nernstove jednadžbe. Iz navedenih rezultata vidimo da odziv potenciometrijskog senzora nije zadovoljavajući za srebrove ione, dok je za kloridne ione prihvatljiv.The aim of this bachelor thesis was to examine the response of potentiometric sensors by measuring concentration of chloride and silver ions under the values of pH=4,00 and pH=4,75 by using ion-selective membranes. The desired response of potentiometric sensors should follow the slope of the line of the Nernst’s equation. From the given results we can observe that the response of the potentiometric sensors is not satisfactory for silver ions, while it is acceptable for chloride ions
