Abstract
In this paper, the effect of ultraviolet light on the [CuL](ClO4)2–glucose (Glu)–acetone (Act)–sodium bromate (NaBrO3)–sulfuric acid (H2SO4) oscillation system was studied. The reaction mechanism and Oregonator model were established to verify the mechanism. Comparison of the bromide ion electrode–platinum electrode correlation diagrams with and without ultraviolet light reveals a nontracking phenomenon in the bromide ion electrode–platinum electrode correlation diagram under illumination, indicating that the illumination will affect the changes in the bromide ion concentration in the system. During the process, as UV intensity increases, the concentration of bromide ions in the system increases, and bromide ions can inhibit chemical oscillations, resulting in a decrease in the amplitude of chemical oscillations, further verifying that the proposed mechanism is reasonable.
Highlights
Oscillatory chemical reactions [1,2], which are very sensitive, are disturbed by various small interfering factors, making them useful as an advanced analytic technique for trace substances.These systems generally include the Belousov–Zhabotinsky(BZ) [3,4,5], Bray–Liebhafsky(BL) [6], and Briggs-Rauscher(BR) [7] oscillation systems
Based on a previous report, to expand the family of photochemical oscillatory systems, we study the H2 SO4 -NaBrO3 -Acetone-Glucose B-Z oscillation system catalyzed by [CuL](ClO4 )2 [16,17] and predict that the system exhibits photosensitivity
The concentrations of sodium bromate, glucose, acetone and [CuL](ClO4 )2 in the oscillating system were optimized under constant light exposure (1250 Lux)
Summary
Oscillatory chemical reactions [1,2], which are very sensitive, are disturbed by various small interfering factors, making them useful as an advanced analytic technique for trace substances. These systems generally include the Belousov–Zhabotinsky(BZ) [3,4,5], Bray–Liebhafsky(BL) [6], and Briggs-Rauscher(BR) [7] oscillation systems. Photochemical reactions [10] are one of the most important reaction processes in the life cycle. Both photosynthesis [11] and visual reactions are photochemical reactions. The study of the effect of light interference on the BZ oscillation system can provide insight into many poorly understood phenomena in biological systems
