Different ions and compounds present in groundwater might influence iron(II) adsorption onto filter media. Laboratory scale batch adsorption experiments were conducted to investigate the effect of major inorganic ions present in groundwater, i.e. Mn2+, Ca2+, NH4+, SO42−, Cl−, alkalinity and background ionic strength on the iron(II) adsorption onto new silica sand and iron oxide coated sand. Alkalinity, background ionic strength, NH4+ and Cl− had no significant effect on iron(II) adsorption onto both the media tested. An increase in concentration of Mn2+ and Ca2+ decreased the iron(II) adsorption onto new sand whereas an increase in iron(II) adsorption was observed when SO42− concentration was increased. The effect of Mn2+, Ca2+ and SO42− on iron(II) adsorption onto iron oxide coated sand, however, was minimal. This indicates that once the iron oxide coating is developed, iron(II) adsorption is not significantly hindered due to the presence of other inorganic ions in concentrations common in groundwater. adsorption, groundwater, iron oxide coated sand, iron removal, water quality This content is only available as a PDF. © IWA Publishing 2002 You do not currently have access to this content.
