  • Cold vapor atomic absorption and fluorescence analysis of mercury

    Creator:
    Hawley, James Edward
    Abstract:
    A critical study of the cold vapor atomic absorption and fluorescence instrumentation for the analysis of mercury is described. Some of the important modifications involve the reduction vessel, absorption cell, fluorescence cell, and radiation source. The new modified systems have much greater calibration sensitivities and lower detection limits than those...

  • An investigation of the crystal growth of the heavy metal sulfides in supercritical hydrogen sulfide

    Creator:
    Lewis, Leroy Crawford
    Abstract:
    Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin,...

  • Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

    Creator:
    Krueger, Carolyn J.
    Abstract:
    Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

  • Analytical method development for the identification, detection, and quantification of emerging environmental contaminants in complex matrices

    Creator:
    Place, Benjamin J.
    Abstract:
    The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...

  • Synthesis and oxidation of metal-thiolate compounds which mimic the active site function of thiolate dioxygenase enzymes

    Creator:
    Schussel, Leonard J.
    Abstract:
    Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...

  • Reaction Pathways of Oxo-Hydroxo Group 5 Clusters to Metal Oxide Thin Films

    Creator:
    Mansergh, Ryan H.
    Abstract:
    Oxo-hydroxo Group 5 metal clusters are an untapped resource to study and advance aqueous solution processing of metal oxide thin films. The tetramethylammonium (TMA) hexatantalate salt (TMA6[H2Ta6O19]) yields dense Ta2O5 films (~95% of the bulk ß-Ta2O5 density) with atomically smooth surfaces (<4 Å root mean square surface roughness). This same...

  • Comprehensive, Low-Cost Wicking Microfluidic Analytical Devices for Clinical Diagnostics and Environmental Analysis

    Creator:
    Bandara, Gayan C.
    Abstract:
    Analytical techniques are utilized in a wide variety of applications. Traditionally, analytical measurements are achieved by trained personnel in a laboratory setting using expensive scientific instruments, which limits their applicability in resource-limited areas and point-of-care applications. Therefore, the concept of enabling these laboratory-based qualitative and quantitative assays in microfluidic device...

  • Synthesis and investigation of layered oxides with honeycomb ordering

    Creator:
    Schmidt, Whitney L.
    Abstract:
    Synthesis and discovery lies at the core of every field in chemistry. The investigation of the structure-property relationships in compounds known or new is the fundamental purpose of solid state chemistry. Mixing related solid state compounds to form solid solutions can lead to exciting new and/or unexpected properties. Layered compounds...

  • Epoxidation of cyclodiene compounds by rat liver microsomes

    Creator:
    Wong, David Taiwai
    Abstract:
    Rat liver microsomes are shown to contain an enzyme system which converts the cyclodiene insecticides, aldrin, heptachlor and isodrin to their corresponding epoxides, dieldrin, heptachlor epoxide, and endrin. The microsomal fraction of 450 milligrams of liver from male rats epoxidates 80 percent of a 20 to 50 microgram aldrin substrate...

  • A three-phase argon plasma arc for analytical emission spectroscopy

    Creator:
    Mattoon, Terence Richard
    Abstract:
    A new three-phase argon plasma arc was developed for analytical emission spectroscopy. The power supplied to the plasma arc utilized a simple circuit with three-phase as line voltage stepped down via a transformer to 104Vrms. A three concentric quartz tubing assembly was determined to be the optimum configuration for supplying...
