Dissolved natural organic matter (NOM) and heavy
metals are abundant in aqueous and terrestrial
systems. Goethite is a ubiquitous iron oxide mineral
found in sediments and aquifers. Sorption processes
involving mineral surfaces largely control the fate,
transport, and environmental impacts of NOM and heavy
metals. An understanding of NOM and metal sorptive
behaviors is therefore helpful in the development of
predictive models. To better understand the
interactions between NOM, heavy metals, and mineral
surfaces, this research (1) implemented a bulk
property approach to study NOM and potential aqueous
complexation between NOM and heavy metals, (2)
studied the mutual effects of NOM and cadmium on
their sorption to goethite, and (3) began to develop
a web-based computer simulator to model NOM sorption
at the mineral-water interface.
