The theme of Sabur’s MSc research is to conduct fundamental science experiments on how organo-arsenic compounds of environmental relevance interact with reactive components in soil, particularly iron (oxyhydr)oxides. Arsenic is released to the environment mainly from natural sources intensified by anthropogenic activities. Due to its varying toxicity, it is essential to know of its interaction with environmental surfaces for risk assessment and cleanup efforts. The main objective was to extract kinetic and thermodynamic parameters that will aid in building accurate mathematical models to be used in predicting the fate of arsenic compounds and in designing arsenic removal technologies. Sabur’s MSc committee concluded that he produced outstanding data from his experiments that is pushing the boundaries of knowledge in field of geochemistry.
