Abstract
The prepared magnetic-modified Fe3O4 nanoparticles (Fe3O4-TAN) were used as adsorbent for removal of crystal violet (CV) from water solution. The effects of pH, contact time, dye concentration and temperature on adsorption were determined. The experimental data were analyzed using the Langmuir adsorption model. The data fitted well to the model with maximum adsorption capacities 84.0 mg/gunder pH=11.0. Also the adsorption kinetics and thermodynamic parameters were studied and evaluated. Adsorption of the CV to nanoparticles reached equilibrium after 15 min. In addition, the external magnetic field could easily separate nanoparticles from water with high separation efficiency.
