| 英文摘要 | Potentiometric microelectrodes are regarded as promising probes for ion sensing when only limited sample volumes are available. In this work, an all-solid-state ion-selective microelectrode (IS mu E) has been developed by coating ionophore-based ion-selective membrane on a poly(3,4-ethylenedioxythiophene)-poly(sodium 4-styrenesulfonate) modified gold wire with a diameter of 14 mu m for detection of copper. Under the optimized conditions, the proposed all-solid-state Cu2+-IS mu E shows a Nernst response toward Cu2+ in 0.5 M NaCl in the range from 2.5 x 10(-7) to 2.5 x 10(-4) M with a detection limit of 4.0 x 10(-8) M. Additionally, the Cu2+-IS mu E has been used for monitoring the vertical distribution profile of Cu2+ in coastal sediment pore water with a small volume (e.g., 300 mu L). The results agree well with those obtained by anodic stripping voltammetry, which indicates that the proposed potentiometric technique based on the all-solid-state IS mu E is promising for detection of Cu2+ in coastal sediment pore water. The method for the preparation of the IS mu E can be extended to detect other heavy metal ions in sediments by using different ion-selective membranes. |
