Abstract
Dye photodegradation using ozone and Nickel ferrite nanoparticle (NFN) as a photocatalyst was studied. The catalyst was synthesized and characterized by FT-IR, SEM and XRD. Textile dyes including Remazol Red RB (RRRB) and Direct Green B (DGB) were degraded as model compounds. Dye degradation was investigated using UV–Vis and ion chromatography (IC) analyses. The effect of catalyst dosage, pH, salt and initial dye concentration on decolorization was studied. Carboxylic acids were detected as intermediates. It can be concluded that Nickel ferrite nanoparticle could be used as an effective catalyst for photocatalytic ozonation of dyes in colored wastewater.
