Arsenic (As) contamination of water has been considered as an issue of great concern. In this study, we developed magnesium hydroxide coated iron nanoparticles (nFe0@Mg(OH)) for enhancing arsenic removal from aqueous solutions. For a practical use, several parameters were investigated, including Mg/Fe coating ratio, nFe0@Mg(OH) dosage, initial pH, reaction temperature, and initial As(V) concentration.
