Arsenic exists as several mineral forms in the earth's crust, and may enter water systems as a result of natural or anthropogenic processes. Ingestion of arsenic can cause a wide variety of health problems such as kidney failure, cancer and heart failure. One promising method for water treatment is sorption onto an iron oxide material, especially a high surface area or nanometric material. The capacity of such materials is necessarily limited to the surface so we have designed a water-insoluble material that can theoretically utilize all of its iron ions a sites to sorb arsenic. An iron coordination polymer, synthesized from ferric chloride and fumaric acid, has been shown to adsorb appreciable amounts of arsenate from water. The performance of other fumarate-based coordination polymers with varying metals will also be discussed.
