A method for preparing a sorbent composition includes the steps of: applying, from a solution or a slurry, a layer of a copper compound on the surface of a support material, and drying the coated support material, wherein the thickness of the copper compound layer on the dried support is in the range 1-200 μm. The precursor may be converted to a sorbent suitable for removing heavy metals from liquids or gases by applying one or more sulphur compounds to sulphide the copper compound and form CuS. |
