Developing an adsorption model for antimony (V) in mine contaminated soils from Cobalt, Ontario
An adsorption model for Sb (V) onto mine impacted soils from the Cobalt, Ontario area was developed. In generating this model the relationship between pH and soluble Sb was investigated. Batch adsorption data showed an increase in soluble Sb after a pH value of 4, with maximum concentrations in solution occurring at a pH of 6. The adsorption of Sb onto a separated clay fraction as a function of pH and ionic strength was also investigated with the results indicating that the maximum amount of Sb adsorbed occurs at a pH value of 6. The model was generated using the proton and Sb binding constants calculated above and those available from the literature. Once completed, the model was then validated using batch adsorption experiments, immiscible displacement techniques and surface water samples collected from the area.
