The Environmental Analytical Chemistry research group within the School of Chemistry at WITS is a dynamic and productive group that focuses on research in water/wastewater, analytical method development and data modelling. The group currently has 50 postgraduate students (MSc & PhD) and two postdoctoral research fellows. Present research projects that use electrochemical methods are utilised for nanotoxicity studies.

The Environmental Analytical Chemistry research team is researching mechanisms and kinetics of free radical formation from functionalised and non-functionalised nanoparticles in simulated body and environmental fluids. One of the electrochemical techniques that can be used is fast cyclic voltammetry (CV) using RDE or RRDE. This technique can capture very short- time living intermediate free radical formation during dissolution or reactions of nanoparticle forms of materials.
