摘要：

Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm(-3) H2SO4 solution by means of polarization measurements and product analysis. It has been demonstrated that it is possible to determine very low concentration of dissolved ruthenium species (8 x 10(-10) mol dm(-3) Ru) by a sensitive spectrophotometric method based on the ruthenium-catalyzed ceric-arsenite reaction. Finally, the probable mechanism of anodic dissolution of RuO2-based electrode, has been proposed. (C) 2003 Elsevier Ltd. All rights reserved.
