Thermal Desorption Of Hazardous And Toxic Organic Compounds From Soil Matrices : Dichloromethane, Chloroform, Benzene, Toluene, 1-Chloronaphthalene, 1, 2, 4-Trichlorobenzene, Arun S. Chemburkar

Theses

This research project was undertaken to understand the process of desorption/removal of organic compounds from soil matrices under the influence of temperature and gas purging. The project was divided in two parts :

A. Plug deposition experiments: Columns packed with soil matrices were purged with an inert gas under isothermal conditions. Organic compounds were then introduced as a plug on the front of the column by on-line injection. The rate of passage (due to sequential adsorption/desorption) of the plug through the various soil matrices was measured by a gas chromatograph equipped with a flame ionization detector (FID). The compounds studied …

The Distribution Of Chlorine And Iodine In Soil In The Vicinity Of Lead Mining And Smelting Operations, Bixby Area, S.E. Missouri, U.S.A., R. Fuge, M. J. Andrews, T. E. Clevenger, B. E. Davies, Nord L. Gale, C. F. Paveley, B. (Bobby) G. Wixson

Iodine and Cl are enriched in soils in the vicinity of the Magmont and Buick lead mines near Bixby, southeastern Missouri. The enrichments, up to 5.6 ppm I and 305 ppm Cl, are against regional background of 1.26 ppm I and 41 ppm Cl. The area of highest I and Cl is thought to reflect a zone of base metal sulphide mineralization occurring about 400 m below the surface. Iodine and Cl are also enriched in soils immediately adjacent to a tailings pond, hence these elements would appear to be leached from this source. A zone of enhanced I values …

A Simple Solid-Phase Electrophoretic Procedure For The Separation Of Plasmid Dna, Linda Ann Simurra

Biological Sciences Theses & Dissertations

A method was developed for extraction of plasmid DNA from bacterial cells embedded in agarose blocks. Cell - containing blocks were treated with various lysing reagents and inserted into the wells of an agarose gel. Upon electrophoresis the plasmid DNA migrated out of the embedding block and into the gel leaving intact chromosomal DNA in the well. This method was tested with various organisms and found to be effective for plasmid isolation. In comparison to "traditional" procedures, this new method is less tedious since chemical separation of plasmids is not required prior to electrophoresis. Also, a higher yield of plasmid …

Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples

School of Biological Sciences: Faculty Publications

Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Degradation Of Aniline And Nitrobenzene In A Photoreactor, Michael Joseph Sowa

Theses

Degradation of aniline and nitrobenzene in aqueuous solutions was studied. Five reaction processes were utilized, including ultraviolet light, ozone, O₂/UV, O₃/O₂/UV, and H₂O₂/UV. A 30 liter semi-batch gas sparged reactor was used for the development of reaction rate and mass transfer parameters in these systems. The results were used to model a continuous stirred tank reactor (CSTR) for the O₃/O₂/UV case. Reasonable agreement was obtained for steady state exit concentrations between the experimental data and those predicted from the model.

Thermal Decomposition Of Dichlorobenzene In An Atmosphere Of Hydrogen And Helium, Mingta Hung

Theses

Reactions of dilute mixtures of dichlorobenzene in hydrogen and in helium were studied in a tubular reactor at a pressure of 1 atm, residence times of 0.04 to 2.7 seconds, and temperature range of 825 to 1000° C. Product distributions at various reaction conditions are measured with a flame ionization detector gas chromatograph, and qualitative analysis of batch samples was also performed by GC/Mass Spectrometry. The major products were observed as the thermodynamically stable species, HC1, Cis), benzene and chlorobenzene. Thermal reaction in helium at 1 second residence time in 1.05 cm ID reactor yielded less benzene and chlorobenzene when …

Water as a Public Resource: Emerging Rights and Obligations (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches, and Charles F. Wilkinson.

This conference focused on the legal rights associated with a broad range of public uses and interests in water including recreation, fish and wildlife protection, and water quality. Evolving legal areas such as the public trust doctrine, instream flow laws, federal reserved rights, and wetlands protection were discussed.

Water as a Public Resource: Emerging Rights and Obligations considered the extension of the public trust doctrine to areas previously not covered by this concept, as well as developments in …
