| description | A novel nitrate solution combustion process for formation of magnetic Mg _0.5 Ni _0.5 Fe _2 O _4 nanoparticles was introduced, and XRD, VSM, SEM, TEM, and BET techniques were employed to characterize the nanoparticles. For Mg _0.5 Ni _0.5 Fe _2 O _4 nanoparticles prepared at 400 °C for 2 h with 20 ml absolute ethanol, the average size and the saturation magnetization were approximately 22 nm and 8.1 A·m ^2 kg ^−1 , respectively. Mg _0.5 Ni _0.5 Fe _2 O _4 nanomaterials were subjected to reactive red 2BF adsorption, and the adsorption performances were investigated. The results revealed that the experimental data fit the Temkin isotherm model and the pseudo-second-order kinetics model, suggesting that the RR-2BF adsorption process was a monolayer-multilayer-associated chemisorption mechanism. The effects of pH on the adsorption capacity and cycle capacity of the magnetic Mg _0.5 Ni _0.5 Fe _2 O _4 nanoparticles for the adsorption of reactive red 2BF were revealed. |
