摘要：
The voltammetric study of 1,7-diamino-3,9-dibutylbenzo[1,2,3-de:4,5,6-d'e']diquinoline-2,8(3H,9H)-dione conducted in 1:1 water-acetonitrile solvent system was compared with modified screen printed electrode (SPE-A) and L in solution phase. L displayed an electrochemically quasi-reversible nature in voltammograms with both the systems and is presented as a novel disposable voltammetric sensor for mercury ions. Both the electrode systems showed sensitivity towards Hg2+ ions with a lower detection limit of 0.61 μM. Magnitude of the voltammetric current with the SPE-A exhibited three times the current obtained with a bare glassy carbon electrode (GC). Kinetic performance of the SPE-A electrode is better than the GC electrode. The morphological studies indicate reusability of the electrodes.
