摘要：

TiO2 nanocrystals had been modified on the surface of the glassy carbon electrode (GCE) with the help of Nafion. The electrochemiluminescence (ECL) behavior of the TiO2/Nafion GCE in aqueous solution was investigated. A possible mechanism about the ECL of TiO2 had also been proposed. The ECL intensity was linear with the dissolved oxygen concentration in the range of 0.30-10.00 mg/L with a detection limit of 0.12 mg/L. The developed method can be applied to detect the dissolved oxygen concentration or biochemical oxygen demand (BOD). (C) 2008 Elsevier B.V. All rights reserved.
