Research summary

Research problems: Co-sorption of heavy metal cations and oxyanions on (oxyhydr)oxides is of high importance as it can significantly affect their environmental fate and pollution remediation. However, as the sorption process involves the interactions among heavy metal cations, oxyanions, and (oxyhydr)oxides, the related co-sorption mechanisms have not been well-explored and are drawing increasing concerns from various research communities. Proposed solution: The proposed research intends to select ferrihydrite and goethite, two ubiquitous iron (oxyhydr)oxides with high reactivity, as representatives of (oxyhydr)oxides, and then systematically examine the effects of various factors (e.g., solution pH, sorption affinity and density of the contaminants) on the sorption behaviors and binding models of the contaminants on ferrihydrite and goethite. To do the work, this research plans to use batch sorption experiments, instrumental characterization, and molecular modelling, to determine the sorption affinity of various contaminants on the sorbents and the microstructure of the resulting sorbents. Objective: The overall objective is to provide novel information for clarifying the co-sorption mechanisms of heavy metal cations and oxyanions on (oxyhydr)oxides. This research can also help in developing novel approaches for pollution remediation of heavy metal cations and oxyanions.

In this research, most of the experimental work will be done in professor Runliang Zhu’s group in Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, while the modelling work will be carried out in professor Steve C Parker’s group in the University of Bath.
