The product has a surface area in the range of 115-145 m.sup.2/g as measured using the BET method. The heavy metal includes mercury and/or lead. Also disclosed is a method of producing the product and a method of adsorbing at least one heavy metal in a liquid using the product.

A multifunctional hybrid material based on sepiolite for environmental recovery and bio-remediation is described. In particular, the invention describes the design and development of suitably functionalized hybrid nanomaterials starting from sepiolite and the subsequent study of the absorbent and degrading properties in relation to aromatic hydrocarbons, by activating hydrocarbon-clastic bacteria. These nanomaterials have been prepared in order to remove hydrocarbon pollutants (e.g. oil) in natural matrices (marine environment), with potential applications in the field of environmental remediation.

A bleaching clay product, a method of producing and a method of decolorizing an oil are disclosed. The bleaching clay product comprises attapulgite that has been thermally activated. The bleaching clay product may have a permeability in oil in the range of 0.04-3 darcy and may have a surface area of 45-140 m.sup.2/g. The method of producing such bleaching clay product may comprise thermally activating a material that includes attapulgite by heating the material at a temperature in the range of 300 to 900° C. The method of decolorizing may include contacting for a contact time an oil with the bleaching clay product that comprises attapulgite that has been thermally activated, and separating the bleaching clay product from the oil to recover a decolorized oil that has a lower red color than the oil had prior to the contacting.
