Abstract: Equations were developed to predict arsenate sorption on iron oxide coated sand, on the basis of the constant capacitance surface complexation model, assuming formation of bidentate surface complexes between arsenate and ...

Abstract: Efforts are being made to devise technologies and treatment systems to remediate contaminated soil on site without generating significant wastes for off‐site disposal. Heap leaching, a technique used extensively in the ...

Abstract: Agricultural soils of southern New Mexico, especially sand and sandy loams receiving numerous nitrogen (N) fertilizations, are prone to leaching large amounts of N to shallow groundwater. Adsorption and leaching experiments ...
