Various adsorbents have been explored to mitigate this issue, with biochar emerging as a promising candidate due to its high adsorption capacity and environmental sustainability. In this study, we investigated the effectiveness of iron-modified biochar as an adsorbent for arsenic removal from aqueous solutions. The results demonstrated that the ironmodified biochar exhibited superior arsenic adsorption performance compared to unmodified biochar. The maximum reduction was found to be 71%, indicating a significant improvement over conventional biochar. |
