  • Techniques of solvent extraction of organic material from natural waters

    Creator:
    Cronin, John Thomas, 1935-
    Abstract:
    Manual and automatic solvent extraction techniques were used to concentrate organic material from natural waters. Field and laboratory extractions were compared to determine the most probable method and best solvents for efficient concentration of organic material from estuarine and sea waters. The large scale extraction processes utilizing extractors made from...

  • A photoactivable microfluidic device for heavy metal ion extraction

    Creator:
    Nammoonnoy, Jintana
    Abstract:
    The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water. Through integration of the beneficial characteristics of both...

  • Magnetic particles for selective extraction of trace analytes in microfluidic devices

    Creator:
    Tennico, Yolanda H.
    Abstract:
    The development of micro total analysis systems (µTAS), also called “lab-on-a-chip”, or microfluidic analysis systems, is presented in this dissertation. Various research areas, covering subjects from magnetic particles synthesis to novel microchip fabrication techniques, are explored to develop a lab-on-a-chip system capable of performing magnetic bead-based bioassays. These devices are...

  • Extraction and quantification of vitamins from raw, HTST, UHT, and PATP milk and of diatom-produced chitin and glucosamine

    Creator:
    Chotyakul, Nattaporn
    Abstract:
    Analytical chemistry is an essential qualitative and quantitative tool to describe foods and biomaterials and their changes during production, processing and distribution. In this work, rapid analytical procedures for the extraction and quantification of components in fluid milk and diatom fermentation broth were developed. Analytical methods to measure the concentration...

  • Modeling in-situ vapor extraction during flow boiling in microscale channel

    Creator:
    Salakij, Saran
    Abstract:
    In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...
