The effect of different concentration of gallic acid (GA) on the oscillatory behavior of the Briggs-Rauscher (BR) reaction is reported. In this work, the sample was injected before the start of oscillations. The main effect is the appearance of an induction time that increases with the concentration of GA added. Other parameters as a number of oscillations and oscillatory period are
affected. These latter linearly depend on the concentration and can be used for quantitative GA analytical assay in a GA concentration range 3.00×10-5 M − 4.00×10-4 M. The perturbation is very different from that previously reported, in which samples of phenolics were added to an active BR mixture, indicating that the mechanism of perturbation largely depends on the injection point.
