Description
| - 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 presented also 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.

- Značný počet reakčních systémů vykazujících oscilace v průtočném reaktoru je založeno na oxidaci sloučenin síry jako jsou siřičitany a thiosírany různými oxidanty. V naší předchozí práci prezentované rovněž na SSCHE jsme zahájili výzkum mechanismu oxidace těchto sloučenin peroxidem vodíku. Metody určení kinetiky doposud užívané se opíraly hlavně o pH-metrii a zde byly doplněny o infračervenou spektroskopii (FT-IR/ATR). Tato měření poskytují cenné a velmi podrobné informace o časovém průběhu thiosíranu, siřičitanu, tetrathionanu a trithionanu. Uvádíme předběžné výsledky, které ukazují na dobrou shodu s experimenty ve vsádkovém reaktoru. (cs)
