Therefore, speciation analysis of chromium is of great importance to assess pollution levels.
However, exact justification of this association requires subjecting samples to chemical speciation analysis.
Sample treatment is still the most "compromising" step of speciation analysis.
Most of the instrumental techniques used in state-of-the-art speciation analysis require liquid samples.
The proposed method was successfully applied for As speciation analysis in infusions originated from medicinal herbs and tea.
Speciation analysis of trace elements is a relevant topic with involvements in many areas, e.g. environment, food, biology, medicine, etc. Nanomaterials have mainly found application in speciation analysis taking advantage of their sorptive, catalytic or optical properties.
The relative elemental compositions, At%, derived from peak areas are reported for semi-quantitative analysis and Binding Energy, BE, from the peak positions, for qualitative and speciation analysis.
The experiments, using microbiology in combination with aqueous- and solid-phase speciation analysis, were carried out under controlled anoxic laboratory conditions over a period of two months.
The developed method was applied to the speciation analysis of polydisperse environmental samples, in particular, for the separation of soils into silt, clay and sand fractions.
The necessity for the development of these techniques, their interface design, and applications in speciation analysis and metal biomolecule interaction study are reviewed.
The hybrid technique was applied for the speciation analysis of mercury in three certified reference materials, 14 fish, and shellfish samples collected from local markets.
