Abstract

This paper presents the characterization of a sample of mercury jarosite that was synthesized by slowly adding Hg(NO3)2·H2O into a Fe2(SO4)3·nH2O solution. X-ray diffraction (XRD) analysis performed on the sample confirmed that the compound presents a crystal phase corresponding to mercury jarosite. Analysis through Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS) determined that the precipitate is composed of mercury, sulfur, iron and oxygen. It is made up of spherical particles with an average size of 38µm; these particles are made of rhombohedral micro-crystals with sizes ranging between 1 and 2µm. Chemical characterization was performed through dichromatometry analysis, gravimetry and atomic absorption spectroscopy (AAS), thus obtaining the following composition: 27% Fe3+, 37% SO4 2− 14% Hg2+, 22% OH+H3O++H2O. The following approximate formula of the compound was determined from chemical analysis: [Hg0.39(H3O)0.22]Fe2.71(SO4)2.17(OH)4.79(H2O)2.09.
