Magnetic nanoparticles of zinc/calcium ferrite functionalized with silver clusters for photodegradation of dyes
| Resumo: | In this work, magnetic composite nanoparticles of zinc/calcium ferrite and silver were developed and characterized. The nanoparticles were prepared by a co-precipitation method using reflux conditions. The magnetic properties of the synthesized nanoparticles allow their recovery after use in water remediation. The photocatalytic activity of the developed nanoparticles was assessed through irradiation tests in a home-built equipment using visible radiation. Solutions of a model dye (Rhodamine B) and industrial dyes supplied by textile companies (“Red”, “Yellow” and “Blue”) were used for this investigation. |
