Catalysts hydrogen peroxide, Bray-Liebhafsky

The Influence of the Interaction between Catalysts and Hydrogen Peroxide before Initiation of Hydrogen Peroxide Decomposition in the Bray-Liebhafsky System... 

In this series, the catalyst and hydrogen peroxide were mixed before adding to the solution of potassium iodate and sulfuric acid, where, in analogy with other investigations, the moment when two mentioned mixtures were connected was taken as the beginning of the Bray-Liebhafsky reaction. The period of their mutual reaction Q before adding to the solution of potassium iodate and sulfuric acid was different in different experiments. AU other parameters were kept... 

By the presence of either HRP or apFe, the Bray-Liebhafsky reaction is changed in a similar manner. Some amounts of the mentioned catalysts influence decrease, whereas the other amounts influence increase of the characteristic periods Ti and Tend - In other words, some amounts of mentioned catalysts cause the acceleration of the reactions (R), (O), and (D), whereas the other amounts cause their inhibition. Anyhow, by the presence of either HRP or apFe in the BL reaction, the new reaction system for hydrogen peroxide decomposition is formed.
