This work discusses the fabrication, development and potential response behaviors of Ag^+ ion-selective electrodes (Ag^+-ISE) based on N,N’-bis(2-hydroxybenzyl)-1,3-diaminopropane (L1) and N,N’-bis(2-hydroxybenzyl)-2,2-dimethyl-1,3-diaminopropane (L2) as carriers. The observations indicated that the resulting electrode based on L1 toward Ag^+ showed stable near-Nernst slope approaching 58.7 mV/dec and the optimum potential response characteristics in a linear range at least five orders of magnitude with a detection limit of 1.0×10^(-6) M. The proposed electrode displayed the preferential selectivity to Ag^+ against other tested cations. The excellent potential analytical characteristics could lead to the successful applications of silver assay in significant real samples, indicating that the proposed Ag^+-ISE showed a significant advancement of measurement capabilities.
