Iron(III) oxide-hydroxide or ferric oxyhydroxide is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH). The compound is often encountered as one of its hydrates, FeO(OH)·nH₂O [Rust]. The monohydrate FeO(OH)·H₂O (CAS 51274-00-1, C.I. 77492) is often referred as iron(III) hydroxide Fe(OH)₃, hydrated iron oxide, yellow iron oxide, or Pigment Yellow 42.
Complex and manufacturing method for same
Provided are: a novel complex capable of efficiently adsorbing and collecting arsenic (V) dissolved in water; and a novel arsenic adsorbent. This complex contains iron (III)-containing particles supported on microfibrous cellulose. At least a portion of the iron (III)-containing particles has an aspect ratio of 2 or more. The iron (III)-containing particles preferably contain at least one iron compound selected from iron oxides, iron hydroxides, and iron oxyhydroxides. This arsenic adsorbent contains the complex.

Method for producing of composition containing iron-clad nanodimensional graphite
A method for producing an iron-clad graphite composition, which involves plating graphite powder with iron, wherein the plating is carried out chemically, by the action of NaOH on a mixture of FeCl2 aqueous solution and graphite powder at 35-500C, by heating the resulting iron (II) hydroxide-clad graphite at 170-1800C to convert it into iron (II) oxide and then hydrogenating it at 180-2500C to obtain free iron-clad graphite.
