Abstract:

The electrochemiluminescence (ECL) behaviour of a new reagent 10,10'-dimethyl-3,3'-disulfo-9,9'-biacridine (DMDSBA) was studied. The effects of the electrochemical parameters, the reaction medium and pH on the ECL were investigated in detail. It was found that the new reagent DMDSBA gave a strong electrochemiluminescence in KNO3 solution when an appropriate voltage was applied on glassy carbon electrode. Under the optimum conditions, the natural logarithm of the ECL intensity of DMDSBA has a good linear relationship with the natural logarithm of the concentration of DMDSBA in the range of 1.0×10-5-1.0×10-8 mol· L-1, the detection limit of DMDSBA was 2.3×10-9 mol· L -1. The cyclic voltammetry, fluorescence spetrum and ECL spetrum for this ECL system have also been investigated in detail, based on which a possible mechanism for the ECL of DMDSBA was proposed. © Editorial office of Acta Physico-Chimica Sinica.
