Abstract

Ionic liquids (ILs) have garnered much attention in the field of analytical chemistry as tunable solvents with a wide array of applications. Magnetic ionic liquids (MILs) are a subclass of ILs that contain a paramagnetic component in their structure. This paramagnetic feature allows for them to be manipulated by an external magnetic field, possibly reducing the need for centrifugation, which is both a time and labor-intensive process that many analytical extraction techniques involve. Preexisting MILs possess characteristics such as high viscosity and low hydrolytic stability, which are detrimental for their potential use in analytical applications. This thesis introduces design and synthesis of MILs with low viscosity and high hydrophobicity to expand their usability in dispersive liquid-liquid microextraction (DLLME) methods. Furthermore, ILs with varying structures were synthesized for their use in an in situ DLLME method coupled to headspace gas chromatography mass spectrometry (HS-GC-MS) for the rapid analysis of ultraviolet (UV) filters from real water samples. These studies highlight the versatility of ILs and MILs for their application in analytical techniques.
