| 中文摘要 | 9,10-phenanthrenequinone (pq) supported on graphite powder by adsorption was dispersed in propyltrimethoxysilane-derived gels to yield a conductive composite which was used as electrode material to fabricate a pq-modified carbon ceramic electrode. in this configuration, pq acts as a catalyst, graphite powder guarantees conductivity by percolation, the silicate provides a rigid porous backbone, and the propyl groups endow hydrophobicity and thus limit the wetting region of the modified electrode. square-wave voltammetry was exploited to investigate the ph-dependent electrochemical behavior of the composite electrode and an almost nernstian response was obtained from ph 0.42 to 6.84. because the chemically modified electrode can electrocatalyze the reduction of iodate in acidic aqueous solution (ph 2.45), it was used as an amperometric sensor for the determination of iodate in table salt. the advantages of the electrode are that it can be polished in the event of surface fouling, it is simple to prepare, has excellent chemical and mechanical stability, and the reproducibility of surface-renewal is good. |
