Synthesis and characterization of a mesoporous hydrous zirconium oxide used for arsenic removal from drinking water
Powder (20–50 μm) mesoporous hydrous zirconium oxide was prepared from a zirconium salt granular precursor. The effect of some process parameters on product morphology, porous structure and adsorption performance has been studied. The use of hydrous zirconium oxide for selective arsenic removal from drinking water is discussed.We express our thanks for financial support from the Spanish Ministerio de Educación y Ciencia (MAT2006-01997 and Factoría de Cristalización–Consolider Ingenio 2010) and the Gobierno del Principado de Asturias (PCTI 2006-2009).Peer reviewe

Effect of competitive ions on the arsenic removal by mesoporous hydrous zirconium oxide from drinking water
Adsorption properties of 302-type commercially available hydrous zirconium oxide (302-HZO) towards arsenic and some competitive anions and cations have been studied under batch and column conditions. Due to amphoteric properties, anion exchange performance of hydrous zirconium oxide is pH dependent. Media exhibits high affinity towards arsenic in a broad pH range, with high adsorption capacity at pH 8 by using “solid acidifier” technique is discussed. Results of 302-HZO field trials are presented.We express our thanks for financial support from the Spanish Ministerio de Educación y Ciencia (MAT2006-01997 and Factoría de Cristalización–Consolider Ingenio 2010) and the Gobierno del Principado de Asturias (PCTI 2006-2009).Peer reviewe
