英文摘要A single-piece solid-contact Pb2+-selective electrode was prepared by adding a thiophene oligomer into the ion-selective cocktail directly. The one-step fabrication yielded an electrode with Nernstian response spanning a wide concentration range of 10-310-8 mol?L-1, and detection limit as low as 5.6x10-9 mol?L-1. The electrode had a quick response time of approximately 1015 s and showed excellent selectivity over the most common univalent and divalent cations. The practical application of the proposed electrode has been tested by determining Pb2+ in real water samples.; A single-piece solid-contact Pb2+-selective electrode was prepared by adding a thiophene oligomer into the ion-selective cocktail directly.
