Pharmacokinetics of neostigmine and pyridostigmine in man.
Most methods used for the extraction of quaternary amines in biological fluids have been based on ion-pair extraction techniques. In this study, a sensitive and selective chromatographic procedure is described to measure the concentration of pyridostigmine, neostigmine and their major metabolites …

Designed analogues of the aplyronines for use in antibody-drug conjugates
… established sequence, an alternate approach is examined in which the southern and side chain fragments are first connected before the northern piece is appended. The strengths and shortcomings of each route are reviewed. Chapter 4 culminates in endgame manipulations to generate a range of …

Chloramine and MIEX control of disinfection by-products formed from an alluvial aquifer water source
… the DBPs in the drinking water system. Chloramines have been generally used to control the concentration of elevated DBPs species in drinking water distribution systems. However, much of the research on chloramines in DBPs has focused on the surface water sourced water treatment systems. This …

Capturing and Characterizing Soluble Organic Matter Dynamics in Soil Formation Processes
… This thesis has two components, the first examines the potential of using four different resins for the purpose of quantifying time-integrated DOM fluxes across two source (e.g. Douglas fir and Yellow poplar) and concentration (30 and 5 mg C/L) leaf-extracts. The second explores how water …

Surface Modification Of Exhausted Activated Carbon For The Enhanced Removal Of Per- And Polyfluoroalkyl Substances
Granular activated carbon (GAC) is a treatment technology commonly used in drinking water treatment. Recently, a maximum contaminant limit (MCL) has been proposed for a group of per- and polyfluoroalkyl substances (PFAS), a class of chemicals that have been used in many consumer products and …

Development of stationary phase materials and methods for analysis of pharmaceuticals via high-performance liquid chromatography and electrochemical detection
… pharmaceutical solutes is reported. Initially, quaternary amine functionalised fully porous and non-porous silica particles (3 µm) were prepared for subsequent coating with Nafion perfluorinated resin (2 % w/v in ethanol). Elemental analysis (CHN), thermogravimetric analysis (TGA), attenuated …
