Removal Of Heavy Metals From Drinking Water By Adsorption Onto Limestone With A Focus On Copper And Aluminum Applications, Swarna Latha Somasani
Removal Of Heavy Metals From Drinking Water By Adsorption Onto Limestone With A Focus On Copper And Aluminum Applications, Swarna Latha Somasani
Masters Theses & Specialist Projects
Elevated levels of arsenic and other heavy metals like copper, aluminum, zinc, and selenium in drinking water are found to have deleterious effects on human health. Hence, finding methods for reducing their levels is critical. Iron-coated limestone is used as an adsorption material for the removal of heavy metals from drinking water. Removal of heavy metals by native or uncoated limestone was also observed and used for comparison to and evaluation of the improvement in removal efficiency from the ironcoated material. The removal efficiency with limestone was studied for different concentrations of heavy metals. Kinetic studies were done to determine …
An Examination Of White-Nose Syndrome Occurrence And Dispersal Patterns: Utilizing Global And Local Moran's I Analysis To Evaluate An Emerging Pathogen, Celia M. Davis
Masters Theses & Specialist Projects
In this research, a novel approach that utilizes Moran’s I statistical analyses to examine the spatio-temporal dispersal patterns of the White-Nose Syndrome currently affecting North American bat species is undertaken to further understand the disease transmission mechanism(s) of this emerging wildlife epidemic. White-Nose Syndrome has been responsible for in excess of five million bat deaths to date and has the potential to alter the ecological landscape significantly; however, due to a variety of factors, little research has been conducted into the patterns of infection on a national scale. Global and Local Moran’s I analyses were performed on the spatial-temporal variable …
Monitoring Photocatalytic Degradation Of X-Ray Contrast Media With Raman Spectroscopy, Sabina Salkic
Monitoring Photocatalytic Degradation Of X-Ray Contrast Media With Raman Spectroscopy, Sabina Salkic
Masters Theses & Specialist Projects
X-ray contrast media such as diatrizoate and iohexol have been found in wastewater and drinking water and are difficult to remove because they are resistant to water treatment processes. A removal process can be started with ultraviolet photocatalytic degradation of X-ray contrast media in the presence of titanium dioxide or other catalysts. Raman spectra of diatrizoate and iohexol were taken in an aqueous solution in the presence and absence of titanium dioxide during exposure to ultraviolet radiation. Raman intensity is directly proportional to concentration; therefore, we can measure the rate of the reaction based on changes in the Raman spectrum. …
