Activated charcoal was impregnated with cobalt, nickel, copper and zinc. The impregnated charcoals have been studied employing x-ray diffraction technique. Various structural parameters including crystallite size, degree of amorphousness, radius of gyration and density have been calculated from the x-ray diffraction patterns. The results reveal that structural properties of charcoal change upon impregnation with metal ions.
