On Competitive Adsorption of Oxyanions by Soils (Freundlich Equation, Enthalphy of Adsorption, Selectivity Coefficient, Anion Mixtures, Anion)
Abstract
dc:descriptionThe adsorption behavior of anionic mixtures (binary-solute combinations of arsenate, molybdate, and phosphate) by three soil samples (Cecil clay, EPA-14, and Catlin silt loam) was investigated using batch equilibrium techniques. The adsorption of arsenate and molybdate by all three soils was significantly reduced by the presence of phosphate, while the adsorption of phosphate was not greatly influenced by either arsenate or molybdate. The adsorption of arsenate by Cecil clay and EPA-14 was reduced in the presence of molybdate, while arsenate did not compete strongly in molybdate adsorption. In contrast, the adsorption of arsenate by Catlin appeared to be independent of molybdate, while the presence of arsenate lowered molybdate adsorption.
