Adsorption of Cu(II) and Cd(II) by Na-montmorillonite at low surface coverage in the presence and absence of water soluble complexing organic ligands

Creator:: Inskeep, William Parks
Abstract:: The formation of solution and solid complexes with heavy metals will partially determine their mobility and plant availability in soil systems. Experiments were initiated to determine the effect of pH, adsorbent and initial metal concentrations, and the presence of water soluble ligands on the adsorption of Cd and Cu by...

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...

Oxygen absorption in water using a multiple stage crosscurrent packed tower with and without recycle

Creator:: Towle, Betsy
Abstract:: The performance of a multiple stage crosscurrent tower packed with Pall rings was characterized with and without a recycle loop on the gas stream. The column used 12 baffles. The absorption system studied was the transfer of oxygen from an oxygen-enriched air stream into a water stream which is a...

Fluoride sorption and dissolution reactions in soils

Creator:: Peek, Daniel C.
Abstract:: The reaction of F, often a component of industrial wastes and phosphatic fertilizers, with soil was studied with regard to sorption reactions and resultant changes in solution composition. Sodium fluoride solutions (0.0 to 2.5 mmol/L F) were equilibrated with ten soils for 24h. The soil extract solutions were analyzed for...

A kinetic approach for the determination of sorption rate constants using a column-type reactor

Creator:: Patrier, Lionel
Abstract:: A Langmuir sorption model incorporating a second step of irreversible absorption was applied to a model soil system. The column was packed with cellulose triacetate; pulse and step input tests with 3,4-dichlorophenol were performed; the effluent concentration was measured by electron capture detector gas chromatography and sorption rate constants were...

The effect of organic sorbent concentration on sorption kinetics

Creator:: Dolan, Mark E.
Abstract:: Batch sorption tests were conducted using 3,4-DCP and cellulose triacetate as the sorbate/sorbent pair. Sorbate concentrations in the liquid were sampled with time and analyzed by electron capture detector gas chromatography. Sorption was found to be a two stage process characterized by a rapid initial uptake followed by a extended...

Relationship between pore size, particle size, aggregate size and water characteristics

Creator:: Wu, Laosheng
Abstract:: Soil pore size distribution and water characteristics are important for water storage, water movement, and soil-plant interaction studies. Laboratory determinations of water characteristics and pore size distribution are time consuming and costly. Investigators have proposed many models to predict them from routinely available data. Most of the models are related...

Gas absorption in a countercurrent packed tower : (1) Absorption with simultaneous chemical reaction (2) absorption into varying viscous solutions

Creator:: Cho, Jong Soo
Abstract:: The surface renewal rate from Danckwerts' theory and the effective interfacial area between gas and liquid per unit packing volume in a packed absorption tower were evaluated for the absorption of carbon dioxide into carbonate/bicarbonate buffer solution accompanied by a pseudo-first order chemical reaction. The rate of chemical reaction in...

Stability of soil structure for water movement in an aridisol

Creator:: Ali, Safdar
Abstract:: Lack of stability of soil aggregates for water movement is a major problem in arid soils due to low organic matter and higher sodium contents. Soil amendments for improving stability of structure and increasing infiltration of water are essential to solve water management problems in these areas. Different rates of...
