摘要:
In one embodiment, contaminates are removed from a material by contacting an activated carbon fabric wetted with a solvent with the surface of the material. The activated carbon fabric is maintained in contact with the surface in a substantially vapor-tight environment to allow the solvent to dissolve the contaminants, the contaminates to diffuse in the solvent, and the contaminates to be adsorbed by the activated carbon fabric. Thereafter, the activated carbon fabric containing the contaminates is removed and the any remaining solvent is allowed to evaporate. In another embodiment, contaminates are removed from a material by maintaining a solvent wetted fabric in contact with the surface of a material, while exposing at least an upper face of the fabric to a surrounding environment to promote evaporation of the solvent. The evaporation of the solvent from the upper face migrates contaminates from the surface into the fabric where they are contained.
