Cyclic voltammetric investigation of calcium dobesilate (CD) in aqueous acid media was carried out by using an ordered mesoporous carbon-modified pyrolytic graphite electrode (OMC/PGE). A pair of well-defined redox peaks of CD was observed at the OMC/PGE, showing its good elelctrochemial response towards CD. The anodic current is linear with CD concentration in the range of 1.0 X 10(-7)- 1.3 X 10(-3) Mol L-1, with a detection limit of 4.0 x 10(-8) mol L-1. Meanwhile, the proposed electrode can avoid some interference coexisting with CD, such as uric acid, serotonin, and ascorbic acid. The proposed method can be potentially applied for selective electrochemical sensing of CD in physiological condition. (C) 2009 Elsevier B.V. All rights reserved.
