The Briggs-Rauscher (BR) reaction is visually the most interesting oscillating reaction, in which the oxidation of malonic acid by a mixture of hydrogen peroxide and iodate is catalyzed by Mn2+metal ion in acidic solution. It is very sensitive to different analyte addition. Ordinarily,analyte addition causes the linear response of the BR oscillating system, which is used fordetermining the analyte’santioxidant/antiradicalor catalytic activity. In order to investigate the effects of different clay addition on BR oscillatory dynamics, bentonite clays from different deposits: Wyoming (Swy-2), Texas (STx-1b), Idaho (SbId-1), Arizona (SAz-2), Bogovina and Mečji Do, both from Serbia were applied. In the case of bentonite clays addition, the response of the BR oscillating system resulted inacomplex behavior pattern. Meaning that the addition of all investigated clays causeda complex function oscillatory period vs. clay’s mass, which passes through the maximum. The position of maximum varied f...or different bentonite clays. However, it is the first time to obtain such a behavior pattern. Results found areof great importance for the examination of catalytic and heterogeneous phenomena of oscillatory processes in general.
