英文摘要

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 alpha,omega-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-Nemstian slope of 55.1 +/- 0.2 mV/dec and detection limit of 1.7 x 10(-9) mol/L. The fabricated electrodes demonstrated excellent selectivity over the most common monovalent and divalent cations.;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 alpha,omega-dihexylsexithiophene (DH-6T) ion-to-electron transducer.
