Performance of Nano-Magnetite for Removal of Selenium from Aqueous Solutions

“…Adams and Pennington (2005) and Renner (2005) have noted that mining operations and the subsequent processing and utilization of coal and minerals can result in the release of Se as oxyanions into wastewater and mine drainage. In streams impacted by surface coal mining in the central Appalachian basin, the Se concentration was higher (median 12 lg-Se/L) than that found in streams draining undisturbed areas (median 1.5 lg-Se/L) (Neuzil et al, 2007). Parida et al (1977), have found that Se can be present in four different oxidation states-selenide (Se 2 -), elemental selenium (Se 0 ), selenite (SeO 3 2 -), and selenate (SeO 4 2 -)-in aquatic environments.…”

Continuation of Crosscutting Technology Development at Cast

“…In particular, mining operations and subsequent processing and utilization of coal and minerals can result in the release of Se as oxyanions into wastewater and mine drainage (Adams and Pennington, 2005;Renner, 2005). Se concentration in streams impacted by surface coal mining in the central Appalachian basin was higher (median 12 μg-Se/L) than streams draining the undisturbed areas (median 1.5 μg-Se/L) (Neuzil et al, 2007 (Sharmasarkar and Vance, 2002;Benjamin, 1983).…”

Removal of phosphorus/selenium from aqueous solutions by adsorption processes

“…Selenium uptake through food is usually enough to meet human needs. ) (Parida et al, 1996) (Neuzil et al, 2007). In order to mitigate the negative impact, address the increasing public concerns, and meet the more stringent environmental regulations, removal of selenium from aqueous phase, either as selenate or selenite, has been a focus of many recent studies with an aim to develop cost-effective processes.…”
