| 英文摘要 | An all-solid-state polymeric membrane Pb2+ ion-selective electrode (Pb2+-ISE) based on bimodal pore C-60 (BP-C-60) as solid contact has been developed. A BP-C-60 film can be readily formed on the surface of a glassy carbon electrode by electrochemical deposition. Cyclic voltammetry and electrochemical impedance spectroscopy have been employed to characterize the BP-C-60 film. The large double layer capacitance and fast charge-transfer capability make BP-C-60 favorable to be used as solid contact for developing all-solid-state ISEs. The all-solid-state BP-C-60-based Pb2+-ISE shows a Nernstian response in the range from 1.0 x 10 (9) to 1.0 x 10 (3) M with a detection limit of 5.0 x 10 (10) M. The membrane electrode not only displays an excellent potential stability with the absence of a water layer between the ion-selective membrane and the underlying BP-C-60 solid contact, but also is insensitive to interferences from O-2, CO2 and light. The proposed solid-contact Pb2+-ISE has been applied to determine Pb2+ in real water samples and the results agree well with those obtained by anodic stripping voltammetry. (C) 2015 Elsevier B.V.
