Application
Diatomaceous earth may be used as an adsorbent for column chromatography.
It may be used in the synthesis of the following:
It may be used in the synthesis of the following:
- Chitosan modified DE for the abstraction of humic acid from raw water.
- High purity solar grade silicon (SOG-Si).
- Porous silica ceramics.
- Diatomite-based composite with enhanced sorption characteristics.
General description
Diatomaceous earth is natural amorphous silica formed from the fossilized skeletons of diatoms. It has high water and oil absorption ability. The potential toxicity of different samples of DE has been assessed.
