Abstract: Polyoxometalates are metal oxygen containing anions formed
in pH regions intermediate between low pH acidicoxide and high pH XO4
noxoanions. Often, mixtures of various sized anions are formed in synthesis,
and identification of the mixtures is essential to the understanding of
the chemistry of these systems. Various techniques can be used to study
polyoxometalates in pure form, but it can sometimes be difficult to crystallize
polyoxometalates from a mixture. In this project, ion chromatography
and nuclear magnetic resonance (NMR) spectroscopy are going to be
focused on to analyze known and unknown polyoxometalate mixtures.
Ion chromatography will be used because it is a method that separates the
components within the solution and helps to identify the charge and the
number of components present. NMR will be used to determine structural
information about the components and used to verify and support the ion
chromatography results. |
