摘要：

In the present study, the adsorption properties of commercial iron oxide were investigated via chromate and phosphate uptake in aqueous solutions. A series of batch experiments were performed to study the influence of adsorbent dose, pH and contact time. The obtained results show that the removal efficiency of chromate is more important than phosphate. The maximum adsorption rate is observed in pH range [3-4] and [4-5] for phosphate and chromate respectively. In the two cases, the adsorption is slow. The application of the various kinetics models to the experimental data reveals that the second order model is more appropriate in the two cases.
