The contamination of ground water by fluoride and arsenic has recently considerably increased, especially in some regions of India. In this context, the development of efficient adsorbents for the control of fluoride and arsenic, which are the common pollutants in wastewater, assumes significance. Herein, we describe the synthesis, characterization, and application of bi-metals (Fe and Al) doped micro- and nanoparticles based adsorbents for the removal of fluoride and arsenic(V) ions from water. The adsorbents were prepared by suspension polymerization. Fe and Al were incorporated during a polymerization step. The bi-metals doped beads (~.8mm) thus prepared were carbonized and activated to. Highlights: Al and Fe incorporated into polymeric beads during suspension polymerization. Nanoparticles synthesized by simple ball-milling of beads. High loading of F- and As(V) on Al and Fe doped nanoparticles based adsorbents.image.
