【Abstract】 This paper presents a study of the concentration range of reactants of oscillation reaction in Tartaric acid-Glucose-KBrO3-MnSO4-H2SO4-Propanone system. It has set up a new B-Z reaction system with a typical oscillating wave . Effects of many factors on the oscillation have been examined. The period and preoscillatory time as function of the initial concentration of each reaction have been studied. The relationship equation between period and concentration and the apparent activation energy have been got .The oscillation reaction model and reaction mechanism have been established. It is composed of produced Br2, used up Br2 and Mn2+ catalysis unit.更多还原
