Photochemical transformation of particulate organic carbon and its impact on mercury cycling in aqueous systems
… examined how photochemical processes impact Hg adsorption through chemical alteration of POM. Mercury adsorption to irradiated and non-irradiated POM was examined through performing isotherm experiments, using an environmentally-relevant range of Hg concentrations (2-500 ppb). First, we find …

Heavy metal adsorption on iron oxide and iron oxide-coated silica : macroscopic, spectroscopic, and modeling studies
… silica and goethite surfaces are important for adsorption. The sub-micrometer-sized coatings exhibited a larger capacity for metals ions than discrete ones and, although in low concentration, they greatly affected metal affinity to the coated media. X-ray absorption spectroscopy (XAS) analysis …
