Uses

Yellow iron oxide (CAS 51274-00-1) is used as a pigment, e.g. Pigment Yellow 42 or C.I. 77492. Pigment Yellow 42 is Food and Drug Administration (FDA) approved for use in cosmetics and is used in some tattoo inks. Solid material color ranges from yellow through dark-brown to black. Iron oxide-hydroxide is also used in aquarium water treatment as a phosphate binder.Recently, two forms of Iron oxide-hydroxides nanoparticles were identified as very good adsorbents for lead removal from aquatic media.
