Abstract

Activated biochars were obtained from peanut shells, a waste from the local agricultural industry, and used as supports for iron species. These materials were evaluated as catalysts in photo-Fenton reactions for methyl orange degradation in aqueous solutions. Supports and composites were physiochemically characterized by various techniques for better knowledge, finding a good interaction between the active phase and the support. The materials were subsequently evaluated in a batch system equipped with a Hg lamp. The catalysts showed good performance in the degradation of an organic dye. Reuse was evaluated for the catalyst with the highest activity (CA-FeWI), showing a slight loss in photodegradation capacity.
