Creator:: Azizian, Mohammed F.
Abstract:: Chromium and its compounds are widely used by modern industries, resulting in large quantities of this element being discharged into the environment. To remove chromium from contaminated soils and ground water, it is necessary to predict chemical and physical processes that control the rate of reactions and transport of chromium...

Creator:: May, Michael Lee
Abstract:: Several potential sorbent materials containing iron oxides were prepared and evaluated for potential to remove divalent metals from waste waters. These included a ferrihydrite-coated sand, maghemite incorporated in Dowex[Trademark] ion exchange resin, gothite and two thermally activated ferrihydrites. Attempts to prepare sorbents from steel shot by coating with ferrihydrite or...

Creator:: Yang, Maoyu
Abstract:: Studies were undertaken of the adsorption of chlorinated phenols from aqueous solution on granular activated carbon (Filtrasorb-400, 30x40 mesh). Single-component equilibrium adsorption data on the eight compounds in two concentration ranges at pH 7.0 fit the Langmuir equation better than the Freundlich equation. The adsorptive capacities at pH 7.0 increase...

Creator:: Bean, Gregory R.
Abstract:: Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

Creator:: Schroth, Martin Herbert
Abstract:: Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...

Creator:: Ball, Bruce L.
Abstract:: Soil column studies were performed on a chromium contaminated soil from the United Chrome Products Superfund Site currently undergoing a pump-and-treat cleanup process. The goal of the research was to provide insight into the feasibility of chemically changing the injection fluid of the pump-and-treat system to enhance hexavalent chromium (Cr(VI))...
