“…13 Several other researchers have improved on the idea by adding different catalysts or inhibitors to the reaction for the determination of Fe(CN)6 [3][4][5][6][7][8][9][10][11][12][13][14]15 and Mn(II). 16 Recently, oscillating systems involving no halogen compound (particulary the CuSO4-catalyzed reaction of hydrogen peroxide with thiocyanate ion) have aroused increasing attention. 17 The Pérez-Bendito research group used this system for the determinations of glutathione, 18 vanillin, paracetamol and ascorbic acid, 19 gallic acid and resorcinol.…”

“…The mechanism for this oscillating system reaction was established from previous investigations by several authors [6][7][8][9][10][11][12][13]. The oscillation reaction of the H 2 O 2 -KSCN-CuSO 4 -NaOH system consists of 30 kinetic reactions using 26 independent variables.…”

This paper reports a new methodological approach for investigating oscillating chemical reactions using simple and fast analytical information by measuring the conductivity of the solution. Although this technique is very common, and one of the simplest methods among the analytical techniques, however no work has been reported so far using this method for studying an oscillating system. For measuring conductivity, we use the oscillating system of H 2 O 2 -KSCN-CuSO 4 -NaOH. Results indicate that the conductivity of the system fluctuates during the oscillating reaction. The oscillating conduction of this system was studied by changing the concentration of species involved in the oscillating reaction. Results indicate that the oscillating behaviour is varied by changing the concentration of the species.

“…Using this system and the continuous-flow stirred tank reactor (CSTR) which was widely used to ensure the oscillating reaction to be permanently far from thermodynamic equilibrium, Pérez-Bendito D. research group developed the 'analyte pulse perturbation' (APP) technique [15] and applied it in many determinations. In the regular oscillations or even in the chaotic regimes, the characteristics of oscillating chemical reactions including the induction period, oscillating amplitude and oscillating period would have changes which were always correlated with the concentration of the analyte [16].…”

In this paper, a named oscillation frequency spectrum (OFS) was developed for the frequency analysis of oscillating signal. Various complexing oscillating chemical reactions, which have been widely applied to analytical determination, were examined. The OFS extracted frequency information of these systems successfully and distinguished their respective frequency characteristics clearly. The details were such that the Belousov-Zhabotinskii (B-Z) system had three frequency peaks and the Cu(II)-catalyzed system had two. Every periodic signal had a special OFS. Even if the frequency values of two different signals were identical, their OFS figures were distinct. The OFS realized the extraction and calculation for the multifrequency characteristic of oscillating chemical system accurately. It followed that OFS could be used to analyze the frequency of periodic signal with accuracy and was suitable for many areas.
