Description
Summary:The main objective of this work was to study the decolorization of the rhodamine B in aqueous solution using Fenton process. Ls-5000 chelating resin loaded Fe2+ Fenton reagent was prepared by shaking impregnation method. The effects of various factors on the treatment of rhodamine B were preliminarily investigated. The results show that the optimal process conditions for photo-assisted heterogeneous Fenton decolorized rhodamine B with Ls-5000 chelating resin loaded Fe2+ is: 0.60g Ls-5000 chelate resin loaded Fe2+ + 1.5mL H2O2 + 60W visible light power + solution pH=2. 96.21% of decolorization efficiency could be achieved after 180 minutes under the Ls-5000 chelate resin loaded Fe2+/H2O2 reaction system.
