When pH probe was applied to study the ClO2^- - S2O3^2- nonlinear reaction system, batch pH oligooscillation and CSTR pH oscillation were obtained. The reaction mechanism consists of oxychlorine reactions, oxychlorine-sulfur reactions and sulfur-sulfur reactions. A model resultedform valence change of sulfur can simulate the dynamics in both batch and CSTR, and it also can explain the pH front in reaction-diffusion system.
