Abstract EN
Investigation of the adsorption of Chromium (VI) on Fe3O4 is carried out using batch scale experiments according to statistical design using a software program minitab17 (Box-Behnken design).
Experiments were carried out as per Box-Behnken design with four input parameters such as pH (2-8), initial concentration (50–150mg/L), adsorbent dosage (0.05–0.3 g) and time of adsorption (10–60min).
The better conditions were showed at pH: 2; contact time: 60 min; chromium concentration: 50 mg/L and magnetite dosage: 0.3 g for maximum Chromium (VI) removal of (98.95%) with an error of 1.08%.
The three models (Freundlich, Langmuir, and Temkin) were fitted to experimental data, Langmuir isotherm has better described the adsorption process.
Whereas, the kinetics results of the adsorption process obeyed the pseudo-second-order.
