On the basis of the study of non-catalyzed oscillating reaction of red tea system, the non-catalyzed oscillating reaction in Golden Flower Black Tea-KBrO 3-H 2SO 4 system was studied. Effect of reactants concentration (Golden Flower Black Tea, KBrO 3, H 2SO 4) and reacting temperature were investigated, and the difference between the catalytic reaction and the non-catalytic reaction was analyzed. The activation energy of the non-catalytic reaction of Golden Flower Black Tea was calculated to 90.43 kJ/mol. When the concentration of Golden Flower Black Tea was 20.016 mg/L, the concentration of H...
