A study of a new type of the fast renovated, imperishable voltammetric sensor - the bismuth bulk annular band working electrode (BiABE) - applied for molybdenum(VI) determination via differential pulse adsorptive stripping voltammetry (DP AdSV), preceded by complexation of chloranilic acid (CAA) in an acetate buffer (pH 4.0), is reported. The proposed procedure is based on simple and fast regeneration of the BiABE's surface in the presence of testing solution, by application of the activation potential. Optimization of the experimental conditions included potential and time of activation, kind of the supporting electrolyte, pH, potential and time of accumulation, DP mode parameters. Influence of nonionic surfactant on the Mo(VI) signal response in the presence of XAD-7 resin was also tested. The peak current was proportional to the concentration of Mo(VI) over the range from 0.1 to 7 mu g L-1 (1.0 x 10(-9) to 7.3 x 10(-8) mol L-1) with R = 0.9994, for accumulation time of 20 s. For 20 s of accumulation time, the detection limit was 0.02 mu g L-1 (2.1 x 10- 10 mol L-1) (at S/N = 3), and sensitivity was 0.049 mu A/mu g L-1. The relative standard deviation for 1 mu g L-1 of Mo(VI) was 2.3% (n = 5). Finally, the proposed method was successfully applied to determine Mo(VI) in the certified reference waters (SPS-SW1 and SPS-SW2), Humber river sediment (HR-1), as well as the spiked tap and river water samples.
