Zastosowanie spektrometrii atomowej i spektrometrii mas w badaniu specjacji chemicznej

Selected examples of studies conducted by the research group from Laboratory of the Basic Aspect of Analytical Chemistry (Faculty of Chemistry, University of Warsaw), related to the investigation of chemical speciation with the use of coupled techniques were discussed in this work. The pioneering investigation was focused on the study of the speciation of mercury in fish tissues and in clinical samples. Then, the intensive researches were conducted towards understanding of the speciation of antimony and selenium in water, plants and clinical objects. Interestingly, the evaluation of the speciation of aluminium become a challenge in respect of the establishing of the reliable analytical procedure, and the use of flow injection for sample operation were explored in this case. The last but not least, the non – routine analytical procedure was developed in the case of zinc speciation in plant exposed to the harmful environmental conditions.
