Abstract
The spatiotemporal dynamics of the hydrogen peroxide-thiosulfate-sulfite-perchlorate acid system was investigated in reaction-diffusion medium. In the Petri dish, pulse waves were discovered, which had the maximum life-time and the maximum traveling distance when the initial concentration of thiosulfate was increased. In addition, pulse waves contracted back before disappearing, and the pulse waves with red spot were observed when the initial concentration of hydrogen peroxide was higher. The experimental results were analyzed and explained according to the reaction mechanism of positive and negative feedback in this system.
