【 摘 要 】

This review reportsthe use of solid amalgam electrodes in the electroanalytical determination oforganic and inorganic compounds. The different types of amalgam electrodes arepresented, and attention is paid to solid amalgam electrode, and here is presenteddetails about the pre-treatment for activation and renovation and also possiblemodifications in its surface. The wide potential range, higher signal-to-noiseratio, mechanical stability enabling their application in flowing systems, andprincipally their resistance toward passivation, indicate that the solid amalgamelectrodes are environmentally friendly alternatives to mercury electrodes,without loss in the sensitivity and reproducibility in voltammetric responses.
