Description
Summary:[Display omitted] ► Nickel–zinc ferrite magnetic nanoparticle (NZFMN) was synthesized and characterized. ► Dye degradation by photocatalytic ozonation using NZFMN was studied. ► Formate, acetate and oxalate were detected as dominant dye degradation aliphatic intermediates. ► Nitrate, sulfate and chloride ions were detected as mineralization products of dyes. ► NZFMN was an effective magnetic nanocatalyst to degrade dyes. In this paper, nickel–zinc ferrite magnetic nanoparticle (NZFMN) was synthesized and its dye degradation ability using photocatalytic ozonation was investigated. The NZFMN was characterized by X-ray diffraction (XRD), scanning electron microscopic (SEM), Fourier transforms infrared (FTIR) and alternative gradient force magnetometer (AGFM). Reactive Red 198 (RR198) and Direct Green 6 (DG6) were used as dye models. UV–vis and ion chromatography (IC) analyses were employed to study dye degradation. The effects of operational parameters on decolorization such as NZFMN dosage, dye concentration, salt and pH were studied. RR198 and DG6 were completely decolorized (100%) by photocatalytic ozonation using NZFMN. Formate, acetate and oxalate anions were detected as dominant aliphatic intermediates. Nitrate, sulfate and chloride ions were detected as mineralization products of dyes. Results showed that the photocatalytic ozonation using NZFMN was a very effective method for dye degradation.
