Auger parameter measurements of zinc compounds relevant to zinc transport in the environment

Abstract

Abstract This paper reports x‐ray generated photoelectron and Auger transition data for Zn compounds that have not been previously examined by XPS, with the objective of establishing a self‐consistent data base for Zn compounds of environmental and geochemical importance. Additional Zn compounds were analyzed to allow comparison with existing Zn data. Specimens analyzed include: hydrozincite (Zn 5 (OH) 6 (CO 3 ) 2 ), sphalerite (ZnS), smithsonite (ZnCO 3 ), willemite (ZnSiO 4 ), franklinite (ZnFe 2 O 4 ), ZnO, Zn(OH) 2 , ZnCl 2 and Zn metal. Where possible, this data has been related to previously reported values using Wagner chemical‐state (modified Auger parameter) plots. This self‐consistent data base has been used to identify the Zn solids that form on CaCO 3 in Zn 2+ –CaCO 3 suspension.
