Arsenic removal from water with functionalized magnetic nanoparticles

Project Summary: The current project will involve attaching AB9 (the carboxylated derivative of B9, BDTH2-COOH) to silica-coated magnetic nanoparticles (MNPs) in order to prepare a solid reagent with high capacity for arsenic binding and ease of isolation from water. This study will demonstrate the ability to control the size (smaller/similar size for better efficiency) and homogeneity of silica coated particles. The project combines an emerging magnetic nanotechnology while enhancing the understanding of arsenic filtration. This approach will allow transferable water filtration media with the simple introduction of a magnetic field.
