Arsenopyrite oxidation - A review
TL;DR: A review of the existing knowledge of arsenopyrite oxidation is presented in this paper, based on a survey of existing literature, which has focused on processes and reactions at the mineral surface.
XPS study of chemically etched GaAs and InP
TL;DR: In this paper, the surface compositions of GaAs and the binding energy of the surface As atoms vary with the etching solution and with the extent of oxidation of the surfaces, and the full width at half-maximum of the Ga(3p) photoelectron peak increases upon exposure of etched GaAs to air.

The role of silicate in the adsorption/desorption of arsenite on goethite
TL;DR: The importance of anion displacement as a mechanism for arsenic release was examined through the competitive adsorption and desorption of arsenite on goethite in the presence of silicate.
Journal ArticleDOI
Complementary arsenic speciation methods: A review
TL;DR: In this article, the use of X-ray absorption spectroscopy (XAS) with HPLC-ICP-MS can be used to identify compounds not extracted for HPLC, and provide minimal processing steps for solid state analysis that may help preserve labile compounds such as those containing arsenic sulfur bonds.
