Dear AMMRL,
A faculty here has a question on an unusual (to me at least) application of
solid state NMR. They will be sorbing individual organic standard
compounds to cleaned clays (kaolinite, beidellite, montomorillonite, and
illite). They are specifically interested in binding of the organic matter
to the minerals and wondering if it is feasible to use 13C-NMR to detect
this binding, i.e. on these or similar systems does binding result in a
change in the 13C-NMR chemical shifts of the organic standards (amino acids
and various phenols)? If so, any guesstimate of what percentage of the
carbon in the sample would have to be involved in these organic-mineral
interaction to be able to see a change in the C13 chemical shifts? Your
insights would be greatly appreciated!
