Abstract

To obtain large porous iron oxide particles for application to arsenic adsorbents, hydrated iron phosphate particles of strengite (FePO4·2H20) were synthesized from a solution containing ferrous (Fe(II)) ions and then treated using an alkaline solution. As the size of each alkaline-treated particle is several tens of micrometers, the water filterability of these particles is high. In addition, alkaline-treated particles have a large specific surface, because each particle consists of agglomerated fine maghemite (γ-Fe2O3) particles of several nanometers in diameter. It is concluded that hydrated iron phosphate particles synthesized from a solution containing Fe(II) ions are appropriate precursors.
