Solid-phase extraction on alkyl-bonded silica gels in inorganic analysis.
Solid-phase extraction (SPE) is an effective tool for the preconcentration of trace elements and their separation from various sample constituents. Octadecyl and other alkyl-bonded silica gels are most widely used for these purposes. The fundamentals of the SPE of inorganic ions are reviewed and compared with those of related techniques (liquid-liquid extraction and reversed-phase liquid chroma...
متن کاملStudy on diffusion coefficient of benzene and ethyl benzene vapours in nanoporous silica aerogel and silica aerogel-activated carbon composites
In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...
متن کاملIntroduction to Solid-phase Extraction
We have a sample in front of us. It is of unknown composition, but we know that it is complex, containing anywhere from a few hundred to many thousand chemical components. It is of uncertain physical form perhaps it looks like a liquid, but it has solid particles floating in it. We think that a particular compound is present in that sample, somewhere and in some form, but we don't know how much...
