| Removal of arsenic | |
| The aim of this study is to evaluate the potential for removal of arsenic (III) from groundwater through adsorption mechanisms, using naturally-occurring and low-cost iron oxides. The surface area of the used adsorbent was 3.10 m2/g. Batch experiments were conducted with different amounts of adsorbent (0.5 to 30 g/L). The arsenic solution was prepared using underground water and an As3+ concentration of 100 μg/L. The system was constantly stirred at 150 rpm for 12 hours. The results indicate 100% As3+ removal after 3 hours using a dose of 20 g/L of iron oxides. A dosage of 20 g/L of iron oxides and 2.25 hours or 10 g/L and 5.5 hours of retention time produced water quality in agreement with the international standards (10 μg/L). The maximum adsorption capacity of the material was 164 μg As/g. The concentration of iron ions in the effluent was an average of 0.03 mg/L. | |
