Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

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...

Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

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...
Resource Type:: Masters Thesis
Full Text:: that besides adsorption, chromium(VI) reduction occurred and was the major cause of this non

Soil column desorption studies on a chromium contaminated soil

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))...

Laboratory study of chromium sorption and desorption in undisturbed soil

Creator:: Müller, Heike K.
Resource Type:: Masters Thesis
Full Text:: , reduce adsorption, and increase total chromium solubility. Therefore, the mobility of Cr(VI) in the

Experimental evaluation and chemical modeling of hexavalent chromium adsorption, desorption, and reduction in a natural soil

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...

Oxygen absorption into water using multiple plunging jets

Creator:: Cho, Choong Hoon
Resource Type:: Masters Thesis
Full Text:: CONSIDERATIONS Hauxwell reported a general relationship between the absorption rate and the jet stream

Absorption of ammonia in water using a multiple stage crosscurrent packed column

Creator:: Zuehlsdorff, DuWayne Aaron
Abstract:: A multiple stage crosscurrent packed column suitable for gas-liquid mass transfer was constructed and operated. The absorption column consisted of a rectangular box constructed of plexiglass and metal. Deflection baffles were positioned at regular intervals on opposite sides of a central packed section to divert the gas phase into the...

Diffusion and surface reaction processes of absorption on surfaces of soil particles in unsaturated soils

Creator:: Yingjajaval, Suntaree
Abstract:: At present the adsorption kinetic of ions by soil particles is considered to be a surface reaction. When the transport of solutes in soils is described using the one-dimensional flow equation, it becomes a serious problem that lateral diffusion of ions from the bulk solution towards the soil surfaces is...

Absorption of oxygen in water using a multi-stage, crosscurrent packed column

Creator:: Davis, Daniel S. (Daniel Scott), 1958-
Abstract:: A multi-stage, crosscurrent column, packed with Pall rings, was employed for oxygen absorption from an oxygen-rich air phase by contacting with water. Mass transfer data were collected for the column using 6 and 12 baffles and employing a partial gas phase recycle. Data were also collected from a countercurrent column...
