Since Bray first discovered in 1921 the periodic oscillation phenomena in decomposition reaction of hydrogen peroxide catalyzed by coupled iodic acid-iodine oxidization, Belousov and Zhabotinskii found in succession the periodic oscillation phenomena in the oxidization reaction of citric acid by potassium bromate catalyzed by coupled Ce~(4+)-Ce~(3+), and Rossler also observed the chaotic oscillation of this reaction. In resent years, some oscillation cases in geochemical reaction systems have also been discovered successively. Zhang Ronghua et al. discovered the chemical oscillation phenomena in dissolution reaction of fluorite. Nonperiodic chaotic oscillation of dissolution reaction of chalcocite in NaCl solutions is also discovered in this study.
