Oxidative Degradation of Rhodamine B Catalysed by Copper Oxide Nanoparticles in Aqueous Medium
In the present work , copper oxide nanoparticles are synthesized by wet sol – gel method using sodium hydroxide as the precipitating agent and starch as the capping agent. Size characterization of the nanoparticle was done by TEM, XRD and FT – IR. The as prepared nanoparticles are used as catalyst in the degradation Rhodamine B dye using hydrogen peroxide.The effects of H2O2 dosage, medium pH, solution temperature, and the dye compositions on the degradation kinetics of rhodamine B have been studied. The pH=4 and temperature = 40◦c are the optimized conditions.
