摘要

Nickel zinc ferrite nanocomposite was synthesized and characterized by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). The XRD patterns confirmed the synthesis of a single crystalline Ni0.5Zn0.5Fe2O4 magnetic nanocomposite. Size of the nanocomposite according to SEM was obtained around 27 nm. Various anionic and cationic dyes were removed from water solutions using the synthesized sorbent. The Langmuir adsorption capacities (q(max)) was found to be 250.0 mg g(-1) for Alizarin, 333.3 mg g(-1) for reactive blue and Janus green B, 500 mg g(-1) for Congo red, crystal violet and methyl violet.
