Abstract: Investigates the role of arsenate and chromate on the dissolution of goethite by oxalate. Oxyanion inhibition of dissolution at near neutral hydrogen-ion concentration values; Impact of mononuclear and binuclear complexes on dissolution; Acceleration of dissolution in an increased negative charge of goethite upon adsorption of oxyanions.
