Tunisia Silica Gel Sand

In this study silica gels were synthesised from Tunisian sands collected from the Fortuna and Sidi Aich Formations in northern and central Tunisia. The collected quart sand raw materials as well as the prepared silica gels were characterised by different techniques such as Xray diffraction XRD X

In order to widen the industrial uses of Douiret sand belonging to the Chenini formation Southern Tunisia experimental investigations have been performed to synthesied the silica gel from the natural raw material using alkaline attack which correspond to the fusion of silica and sodium carbonate together at high temperature 1060 C.

The present work aimed to achieve valoriation of Albian sands for the preparation of sodium silicates that are commonly used as a precursor to prepare silica gel. A siliceous sand sample was mixed with sodium carbonate and heated at a high temperature 1060 176C to prepare sodium silicates.

Generally silica gel is synthesied from the basic material of quart sand which is a source of silica 2. Quart has a large silica content of almost 100 and is crystalline therefore it has a

XRF confirmed that the detrital sand deposits of southern Tunisia contain high amounts of silica with content ranging from 88.8 to 97.5. The internal porosity varied between 17 and 22 and

XRF conrmed that the detrital sand deposits of southern Tunisia contain high amounts of silica with content ranging from 88.8 to 97.5. The internal porosity varied between 17 and 22 and the specic surface area was less than 5m 2 g.

How to dry flowers with sand or kitty litter uses the same process as drying flowers with silica gel. Drying with sand or kitty litter it takes longer and the results are a mixed bag. I found I never really got any consistency with this method. You can use it in a pinch and still get OK results.

Column chromatography is frequently used by organic chemists to purify liquids and solids. An impure sample is loaded onto a column of adsorbant such as silica gel or alumina. An organic solvent or a mixture of solvents the eluent flows down through the column. Components of the sample separate
