More Information
Summary:Sorbent materials contain carbonaceous material that has been activated to form a precursor activated carbon have been subjected to a pretreatment with an acid or a base followed optionally by thermal oxidation are useful for treating water. The sorbent material is made by contacting the precursor activated carbon with a nitrogen source and a metal source, and optionally by thermally oxidizing the precursor activated carbon. The resulting doped precursor activated is also calcined.
