Abstract
A porous activated asphaltene material is described with a method of making and a method of using for the adsorption of a contaminant from a solution. The porous activated asphaltene material may be made by functionalizing solid asphaltene with nitric acid, and then treating the product with a metal hydroxide. The resulting porous activated asphaltene material exhibits a high porosity, and may be cleaned and reused for adsorbing contaminants.
