Název v původním jazyce

DETAILED MECHANISTIC MODEL OF OSCILLATORY REACTIONS INVOLVING HYDROGEN PEROXIDE, SULFITE AND THIOSULFATE

Popis výsledku v původním jazyce

A number of reaction systems that provide oscillatory and other complex dynamics in a flow-through reactor is based on oxidation of specific compounds of sulfur, such as sulfite and thiosulfate, by various oxidation agents. In our previous work presentedalso at SSCHE we started examining mechanisms of oxidation of these compounds by hydrogen peroxide. Techniques used so far for the investigation of reaction kinetics, which involved mainly the use of a pH-meter, were extended by measurements of time evolution of concentration of major components with attenuated total internal reflectance infrared spectroscopy (FT-IR/ATR). These measurements provide valuable and rather detailed information on time evolution of thiosulfate, sulfite, sulfate, tetrathionate, and trithionate. We present preliminary results in graphical form, which show very good agreement with experiments in batch-operated reactions of individual components.
