| Abstract: | Five new bis(benzo-15-crown-5) derivatives with different connecting groups were synthesized. Potassium ion-selective PVC membrane electrodes based on these bis(crown ether)s were prepared and their selective properties were measured. The results showed that most of these electrodes are stable over a wide pH range and their selectivity coefficients were better than those of an electrode based on natural valinomycin. |
| Keywords: | Bis(benzo-crown ether)s PVC membrane potassium ion-selective electrodes neutral carriers |
