Current Research
My current research is aimed at determining equilibrium constants for aqueous metal-ammonia complexes at elevated temperatures up to 300 ºC using UV-Visible spectrophotometry techniques. Ultimately, the equilibrium constants from this work will be fed into databases used by anyone from hydrometallurgists to nuclear power plant operators to accurately model and understand the metal dissolution potential of ammonia-bearing fluids.
