Research Abstract

The porous particles of maghemite are synthesized from hydrated iron arsenite and hydrated iron phosphate particles such as scorodite, strengite and metastrengite. Such particles are candidates of arsenic adsorbents, because these exhibit large specific surface and superior filterability. In this study, arsenic adsorption and arsenic desorption properties were investigated under different solution conditions. The arsenic adsorption capacity was increased with decreasing pH. The arsenic adsorbed on porous particles was desorbed by the immersion in an alkaline solution. In addition, the arsenic desorption was accelerated by the immersion of a metallic iron plate. Such behavior is attributable to the decrease of electrical potential in the solution.
