Complex carbon-mineral sorbents from common clay

Carbon/mineral complexes are materials with surfaces covered partially or totally by carbon materials contains. They have high industrial potential uses as material adsorbents and ceramic filters. The objective of this work is to evaluate the corrosion strength in acid and alkaline solutions, and the adsorption capacity of methylene blue of some materials prepared in the LMPSol. The compositions were prepared with an industrial common clay named "tagua" and organic and inorganic additives from industrial residues up to 50%. The corrosion test was performed in water at 60 degrees C and in aqueous solutions of HCl and NaOH at room temperature, with mass losses measured after 15 days. The samples were pressed manually and heated at different temperatures: 110 degrees C, 350 degrees C and 500 degrees C. The performed tests were transverse flexural strength, porosity and water absorption.
