Iron(III) hydroxide, gamma-phase

Description

CAS: 20344-49-4 | FeHO2 | 88.851 g/mol

Iron(III) hydroxide, γ-phase is used in purifying water and as an absorbent in chemical processes. It is involved in the preparation of iron oxide-hydroxides nanoparticles, which is used as a very good adsorbent for lead removal from aquatic media. It is also used as a pigment, as a catalyst and in aquarium water treatment as a phosphate binder. Further, it is employed in the paints-lacquers-varnishes industry.
