What is FTIR microspectroscopy?

FTIR microspectroscopy is a non-invasive and label-free tool that requires a very limited amount of material and allows obtaining a biochemical fingerprint of the sample under investigation, providing information on the content and structure of its main biomolecules, as well as on their chemical modifications6,7.

What color is Ferrihydrite?

What is FTIR used to determine?

FTIR spectroscopy is used to quickly and definitively identify compounds such as compounded plastics, blends, fillers, paints, rubbers, coatings, resins, and adhesives. It can be applied across all phases of the product lifecycle including design, manufacture, and failure analysis.

How is FTIR spectroscopy used to examine ferrihydrite?

An obvious challenge with the use of FTIR spectroscopy for the examination of the Fe (II)-catalyzed transformation of ferrihydrite is that changes in the size and morphology of the Fe (III) oxides which form can occur following reaction with Fe (II).

Why does ferrihydrite have a high surface area to volume ratio?

In addition to having a high surface area to volume ratio, Fh also has a high density of local or point defects, such as dangling bonds and vacancies. These properties confer a high ability to adsorb many environmentally important chemical species, including arsenic, lead, phosphate, and organic molecules ( e.g., humic and fulvic acids ).

What is the chemical formula for ferrihydrite 6 line?

The six-line form has been classified as a mineral by the IMA in 1973 with the nominal chemical formula 5 Fe 2O 3 •9 H 2O.
