Abstract

Magnetic carbon xerogels composite with Fe₃O₄ nanoparticles (MNPs) prepared by co-precipitation can effectively remove arsenic (As(V) and As(III)) and fluoride ions from groundwater. The optimum conditions for the synthesis of these materials were studied, including the molar ratios of MNPs, and catalyst. Carbonization and post-synthesis treatment with H₂O₂-induced surface modification were applied. SEM and Fe analysis revealed the presence of Fe in the materials. This study provides a promising new method for the removal of arsenic and fluoride from groundwater, with the feasibility of reusing adsorbent and magnetic separation, which could have a significant impact on public health.
