N2 - A new solid-contact Ag +-selective electrode was prepared with 9,10,12,13,24,25-hexahydro-5H,15H,23H-dibenzo[b,q][1,7,10,13,19,4,16] -entathiadiazacyclodocosine-6,16(7H,17H)-dione as ionophore, and α,ω-dihexylsexithiophene (DH-6T) ion-to-electron transducer. The sensor exhibited a working concentration range of 10 -8 to 10 -3 mol/L, with a near-Nernstian slope of 55.1 ± 0.2 mV/dec and detection limit of 1.7 × 10 -9 mol/L. The fabricated electrodes demonstrated excellent selectivity over the most common monovalent and divalent cations.
