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...

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...

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...

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...

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))...

A soil property model for evaluating pesticide movement potential

Creator:: Vogue, Margaret A.
Abstract:: Prevention of groundwater contamination by agricultural chemicals requires an understanding of the complex processes that control pesticide movement below the soil surface. Through this understanding it is possible to try to predict which areas may be most vulnerable to contamination. The many models that have been developed to characterize pesticide...
