The changes produced in an activated carbon by treatment in aqueous solutions of (NH 4 ) 2 S 2 O 8 and H 2 O 2 are compared with the modifications produced by oxygen plasma. These changes are monitored by measuring the textural characteristics (surface areas, porosity, pore size distributions) and s
