文摘In the H 2O 2 KSCN CuSO 4 NaOH reaction system, cupric ion plays an essential role for batch and CSTR oscillation . Since Cu 2+(or Cu+) can be precipitated as CuOH, CuSCN and Cu(OH) 2 , its concentration has a complex influence on the amplitude and initial high flowrate of oscillation. The pH drop resulted from the oxidation of KSCN by hydrogen peroxide inhibited the oscillation. The kinetic nature of oscillation should be the H 2O 2 decomposition catalyzed by cupric and thiocyanate.
