Özet
Two diaza-crown ether compounds were synthesized and evaluated as Ag +-selective carriers in polyvinylchloride (PVC) membrane electrodes of solid-state type. The all-solid-state PVC membrane electrode based on N,N-Dibenzyl-dibenzo-diaza-18-crown-6 exhibited a super-Nernstian response (75±10∈mV per decade) over the concentration range of 1×10-1 to 7×10-6∈M of Ag+ ion and a detection limit of 3×10-6∈M, at a wide range of pH (pH 4-7). The response time of the electrode was fast (less than ∼10s), and it can be used for three months without any significant deviation in potential. The proposed all-solid-state PVC membrane electrodes revealed high selectivity toward Ag+ ion with respect to alkali, alkaline earth, heavy and transition metal ions. A flow-through cell of all-solid-state PVC membrane Ag+-selective electrode based on N,N-Dibenzyl-dibenzo-diaza-18-crown- 6 has also been prepared and applied for flow-injection analysis of Ag + ion in solution. © Springer-Verlag 2003.
