Abstract

Abstract: Conduction layer plays an important role in ion‐selective electrodes (ISEs) with solid‐state transduction. Herein, a lead ISE was prepared with Ti3 C2 as the conductive layer, which has less water film and good anti‐interference ability to O2, CO2 and light. Concentration of lead ions can be quickly determined by detecting the electromotive force of the galvanic cell. In 10 −3 –10 −7 M, the Nernst slope is found to be 28.3±1.02 mV/decade. And the detection limit is 4.4×10 −8 M (n=3). It indicates that Ti3 C2 is suitable for the conductive layer in solid ISEs. Abstract :
