The Briggs-Rauscher (BR) reaction is an oscillating reaction in which the oxidation of malonic acid (CH2(COOH)2) in the presence of hydrogen peroxide (H2O2) and potassium iodate (KIO3) is catalyzed with a metal ion (usually manganese ion (Mn2+)) in an acid solution (HClO4). It is well known that the BR reaction represents a chemical system that is extremely sensitive to the addition of different types of analytes. Every change in oscillatory dynamics, caused by analyte addition, can be used for the assessment of analyte concentration, as well as its potential antiradical activities. The basic idea of this work is to use the oscillatory reaction, as an unusual and novel system for distinguishing different types of insoluble materials such as bronzes, specifically phosphate tungsten bronze (PWB) and phosphate molybdenum bronze (PMoB). Regarding the results obtained, the increasing mass of PWB leads to a significant decrease of BR oscillatory time, while the addition of PMoB has not affec...ted the BR reaction dynamics. The obtained different behavior of PWB and PMoB introduced the BR reaction as a systemdetector for these two types of bronzes. In order to investigate the mechanism of bronzes action in BR oscillatory reaction, the pH and electric conductivity measurements, as well as inductively coupled plasma and the cyclic voltammetry measurements were done. This work extends the practical aspect of the BR reaction for the examination of solid materials. Furthermore, the obtained results open a new section of oscillatory reaction usage in material science and catalysis in general.
