摘要：

A description of the preparation and characterization of 25 mu m diameter modified carbon paste-based Cu2+ ion-selective electrodes are reported. The electrodes have a linear potential response within the 10(-3) to 10(-6) M range and a 16 s response time. A substantial benefit of this new type of ion-selective microelectrode (ISME) is the capability to use them as a dual function tip, in either the amperometric or the potentiometric mode of scanning electrochemical microscopy (SECM). The applications reported also support the usefulness of copper ion-selective carbon paste microelectrodes in SECM potentiometric imaging. (c) 2008 Elsevier Ltd. All rights reserved.
