TL;DR: In this paper, trace element contents (including rare earth elements; REE) and isotopic ratios (S, Pb, Sr, Nd, He and Ar) in stibnite and/or arsenopyrite were analyzed to determine the timing of ore formation and to elucidate fluid origin and evolution processes.

TL;DR: In this paper, a semi-automatic hydride generation device coupled with a microwave-induced argonhelium plasma was used with a 0.5m monochromator for the analysis of germanium, arsenic, selenium, tin and antimony in several complex samples.
Abstract: This paper describes the utilisation of a semi-automatic hydride generation device coupled to a microwave-induced argon-helium plasma that is used with a 0.5-m monochromator for the analysis of germanium, arsenic, selenium, tin and antimony in several complex samples. Incorporated in the system are a condensation tube and a Chromosorb 102 column that are used to separate the analyte species from hydrogen evolved during the course of the generation reaction, and to separate the analytes from condensed contaminants that cause spectral background interferences.Results reported are standard recoveries and relative precision for germanium, arsenic, selenium, tin and antimony in whole blood and in enriched flour. Also reported are arsenic and antimony values for NBS orchard leaves. Results obtained on complex samples are compared with the precision obtained for aqueous standards.

TL;DR: In this paper, the influence of Sb ions, introduced as dopants in α-Bi 2 O 3, on the structure of the oxide polymorph forms obtained at high temperature was investigated.
Abstract: The present study investigates the influence of Sb ions, introduced as dopants in α-Bi 2 O 3 , on the structure of the oxide polymorph forms obtained at high temperature. The structural changes of α-Bi 2 O 3 for compositions in the system Bi 2-x Sb x O 3 (x=0, 0.05, 0,1, 0.15, 0.2), at different thermal treatment temperatures were analyzed by thermal analysis, powder X-ray diffraction and infrared transmission spectroscopy. A tendency of the structure to change to a higher symmetry (monoclinic → tetragonal → cubic) was observed, as the content in antimony increased and the temperature reached 850 °C. The presence of Sb 2 O 3 in the Bi 2 O 3 oxide system promotes an oxygen release from the oxide and enlarges the stabilization domain of the δ-phase.

TL;DR: In this article, the authors presented the development of suitable methodologies for determination of the speciation of antimony in sediment reference samples, using liquid chromatography with a post-column photo-oxidation step and hydride generation atomic fluorescence spectrometry as detection system.
