In this study, Ni-ZnFe 2 O 4 nanoparticles were synthesized by co-precipitation technique and used to remove the chromium (Cr) metal from the industrial wastewater. The synthesized nanoparticles were characterized for their structural properties and morphology by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The average particle size of synthesized nanoparticles was calculated by applying the Scherrer’s formula on the characteristic peaks of XRD patterns. The large surface area, controlled size and well-defined structure of the synthesized Ni-ZnFe 2 O 4 nanoparticles showed remarkable results for wastewater treatment. The characterized nanoparticles were distributed into the industrial wastewater under constant stirring for 20 minutes. The nanoparticles’ suspension was subjected to UV–VIS spectrophotometry for the study of photo-catalytic behaviour of Ni-ZnFe 2 O 4 nanoparticles. The effect of Ni-ZnFe 2 O 4 was investigated under visible light irradiation. Zn doping in Ni-ZnFe 2 O 4 showed remarkable effect on efficiency of Cr removal from the wastewater.
