Aging of impregnated charcoal studied by powder x-ray diffraction.
The effects of aging, naturally and artificially, on the cyanogen chloride capacity of copper and chromium impregnated charcoals were demonstrated by means of an x-ray technique. The results reveal that crystallite growth of water soluble impregnants seems to be the primary cause of the capacity loss.
