A new oscillatory system of S2O82- - ClO2- - S2- is reported. The oscillati
on of Pt potential in CSTR and other nonlinear phenomena of Pt potential, a
nd pH value in close (Batch) system are studied. The autocatalytic procedur
es are analyzed, and the stoichiometric equations of several reaction steps
are suggested. The analysis of the autocatalytic mechanism is accomplished
.
