X-Ray and MAS NMR Studies of the formation of Lepidocrocite from Green Rust and Synthetic Alunites

Two separate projects are currently underway involving solid state inorganic chemistry. The first of these involves synthetic alunites. A research group from Germany claimed in a 2003 paper that they found a new hydrothermal synthesis that yields stoichiometric end-member alunites. We are trying to replicate this synthesis and then study both sodium and potassium alunite with X-ray diffraction and NMR.

The second project begins with the synthesis of lepidocrodite from the addition of phosphate to green rust. The final product will be analyzed with X-ray diffraction and NMR to try to understand how the phosphates bind to the iron (II) sulfate. A side project will also test other iron containing molecules such as iron chloride to see if the phosphate binds to those molecules, and if so how and where, also using x-ray diffraction and NMR.
