Determination of Activation Energy for the Degradation of Rhodamine B in the Presence of Hydrogen Peroxide and some Metal Oxide

In this research, degradation of rodamine B in the presence of (hydrogen peroxide), (hydrogen peroxide+aluminum oxide), (hydrogen peroxide+nano-sized aluminum oxide) and (hydrogen peroxide+iron oxide) was curried out at various temperatures (20, 25, 30, 35 and 40 ºC) to calculate activation energy. The activation energy for degradation of rodamine B in the presence of (hydrogen peroxide), (hydrogen peroxide+aluminum oxide), (hydrogen peroxide+nano-sized aluminum oxide) and (hydrogen peroxide+iron oxide) in studied rang were calculated 40.71, 33.75, 30.72 and 36.60 kJ.mol-1, respectively
