| Abstract: | The nonlinear dynamical behavior for the reaction between iodate and thiocyanate in acidic medium(H 2SO 4) has been studied in a flow reactor (CSTR). In the CSTR, the reaction system displays a sustained oscillation in the potentials of Pt electrode. The oscillatory region is very wide in concentrations. The influences of acidity and metal ions on the present oscillations were studied. The results showed that it is possible for the hydronium but not the metal ion to serve as the catalytic species during the oscillations.[WT5HZ] |
