An Ion‐selective Electrode Based on Ti 3 C 2 Solid‐state Transduction for Rapid Detection of Lead Ion Concentration in Aqueous Solution

Abstract Conduction layer plays an important role in ion‐selective electrodes (ISEs) with solid‐state transduction. Herein, a lead ISE was prepared with Ti 3 C 2 as the conductive layer, which has less water film and good anti‐interference ability to O 2 , CO 2 and light. Concentration of lead ions...

Summary:Abstract Conduction layer plays an important role in ion‐selective electrodes (ISEs) with solid‐state transduction. Herein, a lead ISE was prepared with Ti 3 C 2 as the conductive layer, which has less water film and good anti‐interference ability to O 2 , CO 2 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 Ti 3 C 2 is suitable for the conductive layer in solid ISEs.
