摘要：

Oscillations in redox potential and chemiluminescence of the H2O2-KSCN-CuSO4-NaOH system in the presence of luminol were examined. Parts of the mechanism proposed in the previous studies were evaluated by substitution of SCN with CN . The amplitude of the chemiluminescent oscillations was found to be strongly dependent on the initial luminol concentrations. In addition, the time-series ARMA (2; 1)-analysis with Box-Jenkins algorithm were used to simulate the system and the result is well in accordance with the observed oscillations.
