Abstract:

The effect of concentration of Vitamin B1 on the B-Z oscillating reaction, the use of the analysis and the possible mechanism have been studied. Experiment indicated that Vit B1 has an effect on the shape, amplitude and period of the B-Z oscillating wave. The best reaction condition and the reactant's concentrations are reported. The results showed linear relationship between the changes in the oscillation period and amplitude of the chemical system with the concentration of Vit B1 in the range of 5.10×10-6 2.78×10-4 mol L-1.and the related coefficients are 0.995 and 0.093. The possible mechanism of this reaction has been studied in detail.
