We have generated higher weight loadings of magnesium on alumina by using a Soxhlet extractor to dissolve sparingly soluble solutes. The solvent is recycled over the alumina support so as to continuously impregnate the support with the metal complex. With this device we are able to obtain loadings of MgO on the alumina up to 0.66 wt%. The precursor samples were examined by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and our results indicate that the complex looses the water of hydration upon adsorption and does not appear to form crystallites. We have shown that S0{sub 2} adsorption increases with Mg-loading on the impregnated alun-Linas, with 0.85 additional molecules of S0{sub 2} adsorbed for each additional Mg atom (or MgO molecule) on the surface.
