occurrence of aluminium and phosphorus in iron ores and goethite

  • Competitive Adsorption of Phosphate and Arsenate on Goethite

    The competitive adsorption of phosphate and arsenate on goethite was investigated to better understand the bonding mechanisms for the two ions. The anions were added both simultaneously and sequentially. When added simultaneously, the two ions were adsorbed about equally, with the total surface coverage being slightly greater than for either ion alone.
