General description

Silica gel, highly porous textured matrix are generally used for synthesis of adsorbents. They are corpuscular in structure. Silica surface possess a layer of hydroxyl groups and adsorbed water molecules, which can be removed by drying at high temperature or even by treatment with suitable reagents. Silica gel surface plays important role in catalysis, chemical separation and microelectronic fabrications.

Application

  • Silica gel was used on glass plates for preparative TLC and on aluminium sheets for analytical TLC.
  • Silica gel was used in vacuum chromatography and TLC.
  • Silica gel was used in column chromatography.

Analysis Note

May contain insoluble matter and traces of process residues. Should be washed with solvent prior to use.

In this study, we compared microwave solvent extraction (MSE) to conventional methods for extracting organic contaminants from marine sediments and tissues with high and varying moisture content. The organic contaminants measured were polychlorinated biphenyl (PCB) congeners, chlorinated pesticides, and polycyclic
