Ionic liquid-functionalized silica aerogel as coating for solid-phase microextraction

To improve the extraction performance and mechanical property, a bipyridyl ionic liquid-hybridized silica aerogel was synthesized, and explored as the solid-phase microextraction (SPME) coating. Due to the embedding of the bipyridyl ionic liquid in silica aerogel via the covalent bond, the hybridized material not only provided the three-dimensional and porous structure of the aerogel, and it also possessed good extraction performance of the...
