A new oscillatory system of S~2O~8^2^--ClO~2^--S^2^- is reported. The oscillation of Pt potential in CSTR and other nonlinear phenomena of Pt potential, and pH value in close (Batch) system are studied. The autocatalytic procedures are analyzed, and the stoichiometric equations of several reaction steps are suggested. The analysis of the autocatalytic mechanism is accomplished.
