Abstract:
The Briggs-Rauscher oscillatory reaction is the reaction oxidation of malonic acid in the presence of hydrogen peroxide and iodate in the acidic environment, which is catalysed by ions of manganese. This reaction is very sensitive to the presence of additives and has been used in this paper to test the behavior of phosphate tungsten bronze as well as calcium doped tungsten bronze, obtained by thermal treatment. The addition (0.01-0.08 g) of phosphate tungsten bronze and calcium doped phosphate tungsten bronze has a different effect on the dynamics of the Briggs-Rauscher reaction. In the case of the addition of phosphate tungsten bronze in the Briggs-Rauscher reaction, the linear dependence of the length of the oscillatory period on the mass of the added bronze was obtained, while in the case of addition of calcium doped phosphate tungsten bronze, the complex dependence of the oscillatory period on the mass of the added bronze is obtained.
