Abstract:

Inhibited Ru(bpy)32+ electrochemiluminescence by inorganic oxidants is investigated. Results showed that a number of inorganic oxidants can quench the ECL of Ru(bpy)32+/tri-n- propylamine (TPrA) system, and the logarithm of the decrease in ECL intensity (ΔI) was proportional to the logarithm of analyte concentrations. Based on which, a sensitive approach for detection of these inorganic oxidants was established, e.g. the log-log plots of ΔI versus the concentration of MnO4-, Cr2O72- and Fe(CN)63- are linear in the range of 1 × 10 -7 to 3 × 10-4 M for MnO4- and Cr2O72-, and 1 × 10-7 to 1 × 10-4 M for Fe(CN)63-, with the limit of detection (LOD) of 8.0 × 10-8 M, 2 × 10-8 M, and 1 × 10-8 M, respectively. A series of experiments such as a comparison of the inhibitory effect of different compounds on Ru(bpy) 32+/TPrA ECL, ECL emission spectra, UV-Vis absorption spectra etc. were investigated in order to discover how these inorganic analytes quench the ECL of Ru(bpy)32+/TPrA system. A mechanism based on consumption of TPrA intermediate (TPrA·) by inorganic oxidants was proposed. © 2011 Elsevier B.V. All rights reserved.
