The facile solution combustion and gel calcination process was applied to prepare magnetic Zn 0.3 Cu 0.7 Fe 2 O 4 nanoparticles, and the characterization of the product was analyzed by SEM, TEM, XRD, and VSM techniques. The magnetic Zn 0.3 Cu 0.7 Fe 2 O 4 nanoparticles prepared with absolute alcohol volume of 15 ml at 600 °C were expressed with the average particle size of approximately 60 nm and the saturation magnetization of 39.2 emu g −1 . Where after, Zn 0.3 Cu 0.7 Fe 2 O 4 nanoparticles were applied to remove reactive red 2BF (RR-2BF), and at room temperature, the adsorbance of RR-2BF onto them was examined. The results demonstrated that pseudo-second-order kinetics could well express the adsorption process, and Temkin isotherm conformed to experimental data. The adsorption capacity of the sample could reach 130 mg g −1 , which was greatly affected by pH. The acidic environment was conducive to adsorption while the alkaline environment was conducive to desorption. Moreover, the material had excellent cycling performance.
