  • Aqueous Geochemistry
  • Experimental and Environmental Geochemistry

Research in aqueous and environmental geochemistry at TTU collectively focuses on understanding the chemical reactions between natural aqueous solutions and geologic materials present in the Earth’s crust. 

Aqueous geochemistry studies encompass a diverse spectrum of studies; for example, solid-solution interface studies; investigating surface charging properties of nano-particles, colloids, minerals and other materials; metal, cation and anion adsorption / desorption studies; experimental investigations of mineral dissolution kinetics and equilibria; determining anion speciation within evaporative salts; and investigating metal mobility in acid contaminated soils.

The wide scope of aqueous and environmental geochemistry projects necessitates a varied research approach. Therefore, research projects incorporate experimental studies, laboratory analyses, modeling studies and field sampling. Furthermore, aqueous geochemistry is increasingly inter-disciplinary, consequently, collaboration is undertaken with scientists and engineers from the material sciences, chemistry, water resources, and microscopy imaging center.
