ABSTRACT
ArsenXnp is a regenerable, hybrid media for arsenic (As) removal from aqueous streams, that combines the unique chemistry of hydrous iron oxide nanoparticles with the physical stability of a durable, non-friable, spherical polymeric substrate. ArsenXnp in fact consists of nanoparticles of iron impregnated into the matrix of a special, macroporous strong base anion exchanger. This ideal combination of selectivity and substrate durability makes ArsenXnp an ideal As removal media for municipal water treatment plants as well as point-of-entry (POE) and point-of-use (POU) devices.
