Leist, Michael Andrew (2001) The fixation of arsenic wastes. PhD thesis, Victoria University of Technology.

Abstract

Arsenic has found widespread use as a component in a variety of formulations designed to control or eliminate a variety of insect and fungicidal pests. Arsenical wastes are also often produced during the extraction of metals such as copper, gold, nickel and tin. Consequently, there are large numbers of sites contaminated with toxic arsenic residues. The environmental treatment of arsenic is complicated by the fact that it has a variety of valence states. This, coupled with the plurality of regulatory leaching test variants used, has made it impossible to gauge which of a number of Solidification/Stabilization (S/S) processes are the most effective. Cement based Solidification/Stabilization technology currently provides the most promising solution for the disposal of arsenic wastes.
