Studies of visible oscillating chemiluminescence with a luminol-H2O2-KSCN-CuSO4-NaOH system in batch reactor.

Oscillating chemical reactions are complex systems involving a large number of chemical species. In oscillating chemical reactions some species, usually reaction intermediates, exhibit fluctuation in concentration. Visible oscillating chemiluminescence, produced by the addition of luminol (3-aminophthalhydrazide) to the oscillating system H(2)O(2)-KSCN-CuSO(4)-NaOH, was investigated. In this study the effect of varying the concentration of H(2)O(2), KSCN, CuSO(4), NaOH and luminol was investigated in a batch reactor. We showed that the concentration of all components involved in the oscillating chemilumenscent reaction influenced the light intensity and the oscillation period.
