Abstract. The utilization of magnetic nanoparticles as wastewater cleaners was studied. Magnetite, synthesized and characterized by usual methods was delivered to 10 µM Rhodamine B loaded wastewater model, under UV-C irradiation and hydrogen peroxide supply. The quantification of dye degrading for different time intervals emphasized first order kinetics of Rhodamine B adsorption on 8 g/L magnetic nanoparticles.

Key words: Industrial dye, decolorization reactions, process efficiency.
