摘要
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 cc,a-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.
