Determination Of Isotherms Of Enantiomers On A Chiral Stationary Phase Using Supercritical Fluid Chromatography, Wade Newlin Mack Ii

USF Tampa Graduate Theses and Dissertations

Supercritical fluids provide a robust, tunable environment with favorable transport properties and enhanced solubility. Supercritical carbon dioxide is an environmentally friendly substance that has distinct advantages to traditional solvents used in large scale chemical processing. Ibuprofen is an enantiomeric drug that has been shown to fight prostate cancer and has been used as a mild Alzheimer's disease treatment in the S conformation. Purification of high value products with decreased hazardous material consumption is accomplished by employing supercritical fluid chromatography (SFC). Large scale, single enantiomer purification of pharmaceuticals is dependent on scale-up information. Equilibrium isotherms provide the necessary information to scale-up …

Anaerobic Membrane Bioreactor (Anmbr) For Treatment Of Landfill Leachate And Removal Of Micropollutants, Anh Tien Do

USF Tampa Graduate Theses and Dissertations

To date, most studies on the fate and removal of endocrine disrupting compounds (EDCs) and pharmaceutical and personal care products (PPCPs) in wastewater focus on their fate in municipal wastewater treatment plants, and mostly under aerobic condition. There are limited studies related to anaerobic condition and (to our knowledge) no study on the removal of EDCs in landfill leachate by AnMBR. Moreover, for most studies under anaerobic condition, the removal of EDCs was only reported in the liquid phase; solid phase extraction was not reported, thereby preventing mass balance in the studies.

This research was conducted to investigate the potential …
