This study delves on the chemical wave propagation obtained by a modified Belousov-Zhabotinsky (BZ) reaction in a two-dimensional system under the AOT-emulsion media conditions. The media consist of water, oil (octane), sodium bis-sulphosuccinate as an anionic surfactant, and the reactants containing ferroin and 1,4- cyclohexanedione (1,4-CHD). Results on the concentration dependence of the overall dynamics and wave speeds are presented. The behaviors obtained in this system are analyzed by a suitable mechanism specifically for their reaction systems. These behaviors are then compared with the wave patterns observed under similar systems adopting resin or gel membrane system.
