Methodological and speciation aspects of determination of trace elements in environmental samples by spectroscopic methods: F-AAS, ET-AAS, ICP-OES and ICP-MS

During the lecture the following issues will be discussed:

- biological classification and function of the trace elements;

- justification of the necessity of trace elements determination in the environmental samples;

- sampling, preservation and storage of the environmental samples before trace elements analysis;

- methods of enrichment and isolation of trace elements;

- speciation analysis of the environmental samples, conception of speciation and its significance in the bioinorganic chemistry;

- atomic absorption spectrometry in environmental samples analysis: flow injection analysis, background correction methods, usage of matrix and analyte modifiers;

- Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS), principle of these methods and their application to the environmental, biological and food samples analysis;

- the quality of the analytical result.

The aim of the course is presentation of the whole analytical procedure related to determination of trace elements in environmental samples by spectroscopic methods, such as: Flame Atomic Absorption Spectrometry (FAAS), Electrothermal Atomic Absorption Spectrometry (ETAAS), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The analytical procedure consists of many stages starting from the very important one, which is sampling, concluding on the estimation and calculation of the uncertainty of the obtained analytical result.
