Download citation | catalytic decomposit | hydrogen peroxide has been a bleaching chemical for varied pulp, especially mechanical and deinking pulp it is catalytically decomposed by some transition metals in pulp slurry. Hydrogen peroxide decomposition in acidic solutions is catalyzed by the free ferric ion, fe3+ the following rate law for this reaction is determined by the initial rate method in solutions similar.
The decomposition of hydrogen peroxide liberates oxygen and heat only catalytic quantities of iron ion is needed since peroxide also oxidizes ferrous to ferric ion.
