Removal of arsenic by magnetic biochar prepared from pinewood and natural hematite. (2015, background): “The sorption behaviors and mechanisms of As on hematite have been investigated for various solution chemistry conditions (Goldberg and Johnston, 2001).”
Arsenic removal from water/wastewater using adsorbents--A critical review. (2007, background): “Amorphous Al and Fe oxides, aolinite, montmorillonite, and illite were studied as a function f pH for As(III) and As(V) removal [597].”
Arsenic Removal from Water by Adsorption Using Iron Oxide Minerals as Adsorbents: A Review (2012, background): “This contamination is from mineral dissolution in mining sites, arsenical pesticides, disposal of fly ash, geothermal discharge, agricultural drainage waters from some soils in arid regions, and pyritic sedimentary rocks (mine drainage) in contact with the aquifer (Goldberg and Johnston 2001).”
Aquatic arsenic: toxicity, speciation, transformations, and remediation. (2009, background): “These adsorbents include activated alumina, ion-exchange resins, sand, silica, clays, iron, iron compounds, and organic polymers (Goldberg and Johnston, 2001; Mohan and Pittman, 2008).”
