The aqueous geochemistry of arsenic

the long version

"The purpose of this research project was to carry out laboratory investigations designed to elucidate the geochemistry of various forms of arsenic in aqueous solutions...This information will aid in the prediction of the behavior of arsenic in environments such as pit lakes and acid mine drainage. Moreover, the precipitation of As(III)-sulfides and/or the adsorption of As(II) onto mineral surfaces may represent viable mechanisms for the removal of this toxic element from hydrometallurgical waste streams and containment waters. This report summarizes the results we have obtained during this project (September 1, 1996-August 31, 1999)"--Introduction.
