| Popis: | A Cadmium (II) ion-selective electrode (ISE) based on Thia polymeric crown ether (SPCE-Cd2+) as a membrane carrier in a PVC matrix was successfully built for the determination of Cd2+ ions. Using Dimethyl phthalate (DMP) plasticizer, the electrode showed a Nernstian liner response spanning the range of 1*10-1 to 1*10-7 M with a slope of (28) ±2 mV per decade charge and a detection limit of 1*10-9 M. The sensor has a 10-second response time. The cadmium ion-selective electrode is highly precise in its selectivity for Cd2+ over other cations. Some alkali and transition metal ions have selectivity coefficients in the range of 1 * 10-7 to 1 * 10-1. It worked well as an indicator electrode in the potentiometric measurement of the cadmium ion. |
