Sorel Cement

Here's a patent that deals with it, if it's any help.

Thanks John. It looks like a good starting point as it also references some other patents and literature.

Hello aqua doc,

Check out the list of sites which explain how 'sorel cement' is made........... Ignore the Invention sites, just look at the sites of companies making sorel cement'

Summary Mg(OH)2 was identified as a component of Sorel's cement being a very strong sorbent for uranium. Sorel's cement is a mixture of MgO, MgCl2 and water. The optimal conditions for the adsorption of U(VI) was studied by the batch method. A contact time of 2 hours was found to be optimum.

Maximum U(VI) uptake was observed in a pH range of 5.5-6.5 with a sorption constant of Kads = 0.9 h-1 at initial concentration of 20 ppm.

Polypropylene columns filled with 2 g of Sorel's cement at a mesh size of 35 were used for the preconcentration of uranium by passing 8 l of water containing 10 ppb U(VI). A flow rate of 0.25 ml/min and a bed height of 5 cm were found to be the optimum for the U(VI) separation.

A 5 wt% triphenylphosphine oxide solution in toluene was used as an organic solvent for the separation of uranium from interfering elements such as iron(III) and thorium(IV), prior to spectrophotometric analysis. The determination of U(VI) was accomplished by adding Arsenazo III as a coloring reagent to the solution and using a UV-160A spectrophotometer

I spent quite long periods of frustrating attempts to make the process to give good results, reproducible results, it was tricky as all things are. How ever it is very practical and useful for making so many nice things using Sorel cement. Now what do you want the process for ? will you let me know.
